Television host John Oliver used the latest episode of his HBO programme to examine the growing political and legal disputes surrounding congressional redistricting in the United States, arguing that recent changes to electoral maps and court rulings could significantly influence representation in the House of Representatives ahead of the midterm elections later this year.

During the broadcast, Oliver focused on the nationwide debate over the drawing of congressional districts, describing it as one of the most consequential political issues shaping the upcoming elections. He noted that several states have either approved or proposed new electoral maps that could alter the partisan balance in Congress.

Oliver highlighted developments in Texas, where Republicans currently hold 25 of the state’s 38 congressional seats. He said proposed changes to district boundaries could increase the party’s representation to 30 seats. According to Oliver, the potential shift forms part of a broader national trend in which changes to district maps could produce measurable electoral advantages before votes are cast.

Turning to California, Oliver said voters had approved Proposition 50, a measure that redraws congressional districts in a manner expected to reduce Republican representation by as many as five seats. He noted that similar redistricting efforts are also underway in states including Missouri and Louisiana, reflecting an increasingly competitive political contest over electoral boundaries.

Referring to the complexity of the issue, Oliver joked that the subject required an unusually detailed understanding for a comedy programme, before pointing to projections that the latest round of redistricting alone could allow Republicans to gain between three and twelve additional seats in the House of Representatives compared with previous district boundaries.

Oliver argued that such estimates carry particular significance because Republicans secured only a narrow majority in the previous congressional election. He suggested that relatively small adjustments to district boundaries could therefore have a disproportionate effect on legislative control.

A substantial portion of the programme focused on the treatment of majority-Black congressional districts. Oliver said several of the current legal disputes involve proposals that would divide or eliminate districts in which Black voters form the majority, raising concerns among civil rights advocates about minority political representation.

He referred to events in Tennessee, where legislation approved new congressional boundaries affecting the state’s only majority-Black district. Footage shown during the programme included demonstrations against the measure, with one protester burning a printed image of the Confederate flag. Oliver used the moment to illustrate public opposition to the changes while also adding humorous commentary consistent with the programme’s format.

Oliver described the broader practice of drawing electoral districts to favour a political outcome as gerrymandering, noting that the issue has existed in American politics for centuries. He characterised the practice as placing “a heavy thumb on the scale of who gets elected” rather than allowing electoral competition to develop under politically neutral district boundaries.

He also criticised the way congressional districts are drawn in many states, arguing that existing systems frequently permit elected officials to influence maps that ultimately determine their own electoral prospects.

Oliver pointed to comments made by President Donald Trump during the previous year, when Trump said he wanted Republicans to gain five additional congressional seats in Texas. Oliver noted that Texas Governor Greg Abbott subsequently approved a revised congressional map that would deliver that increase.

According to Oliver, California Governor Gavin Newsom responded by supporting revised district boundaries intended to increase Democratic representation by five seats, effectively offsetting the projected Republican gains in Texas.

Although Oliver said California’s proposal was approved without significant difficulty, he argued that additional Republican-led states had already advanced their own redistricting efforts. He cited Missouri and North Carolina as examples of states where revised district maps were expected to increase Republican representation in Congress.

Oliver also discussed Virginia, where Democrats introduced a proposal that would have produced ten Democratic congressional seats compared with one Republican seat. He noted that the plan generated public attention, including bumper stickers carrying the slogan “Texas Started It,” before the Virginia Supreme Court invalidated the proposal on procedural grounds.

The programme further examined recent judicial developments affecting voting rights. Oliver referred to an April decision by the United States Supreme Court that limited aspects of the Voting Rights Act, saying the ruling reduced legal protections for minority voters in seven states and increased the vulnerability of majority-Black congressional districts during future redistricting.

Louisiana featured prominently in Oliver’s discussion. He said a lawsuit brought by twelve individuals identifying themselves as “non African American voters” argued that the state’s congressional map affected their personal dignity. Oliver stated that Louisiana’s governor subsequently initiated changes eliminating one of the state’s two majority-Black congressional districts.

He noted that Louisiana has six congressional districts despite approximately one-third of the state’s population being Black. Under the revised map, Oliver said, only one district would retain a Black majority. He argued that historical election results indicate Black candidates in Louisiana have faced significant electoral challenges when majority-Black districts have not existed.

Oliver also referred to Tennessee’s revised congressional map, which divided the predominantly Black city of Memphis among three separate districts. He additionally cited Florida, where recently adopted district boundaries could increase Republican representation by between three and four House seats.

Drawing together developments across multiple states, Oliver said Republicans could ultimately gain as many as twelve additional seats in the House of Representatives during the November elections. He argued that continued changes to district boundaries in southern states could further reduce the number of majority-minority districts in future electoral cycles.

Concluding the programme, Oliver argued that legislative reform of voting rights would remain vulnerable unless accompanied by broader institutional changes affecting the judiciary. He referred to proposed federal legislation that would establish staggered 18-year terms for United States Supreme Court justices, providing each president with equal opportunities to make appointments, describing the measure as an initial step toward wider court reform.

The measure requires approval from the Federal Aviation Administration before taking effect, including updates to flight navigation systems and airport signage. Lawmakers have also proposed changing the airport’s three-letter code from PBI to DJT, reflecting Trump’s initials.

The move follows Florida’s approval last year of a plan to donate property in downtown Miami for a presidential library dedicated to Trump. Since relocating from New York in 2019, Trump has resided primarily at his Mar-a-Lago estate in West Palm Beach.In recent months, Trump’s name has been attached to a range of initiatives and institutions, including a planned class of U.S.

Kennedy Center for the Performing Arts added Trump’s name following a restructuring that installed his allies.

The same month, the United States Institute of Peace building in Washington was also renamed after the administration assumed control of the organization.The US Treasury has said American paper currency will begin bearing Trump’s signature later this year, while a federal arts panel recently approved a commemorative gold coin featuring his likeness as part of events marking the country’s 250th anniversary.

The naming push has extended to infrastructure discussions. The White House confirmed in February that Trump had raised the possibility of linking federal funding for a Hudson River tunnel project to support from Senate Democrats, including Chuck Schumer, for renaming major transit hubs such as Washington Dulles International Airport and New York’s Penn Station.

No timeline has been provided for when the airport renaming will be completed, pending federal review procedures.

DeSantis is traveling abroad to Japan, South Korea, Israel and the United Kingdom. The visit to Israel coincides with protests over Netanyahu’s plans to tighten controls on the country’s Supreme Court.

Netanyahu, asked by CBS whether he would meet with DeSantis, replied: “Of course, I’ll meet with everyone. Why not? I’ll meet with Republican governors and Democratic governors.”

DeSantis’ office did not immediately respond to a request for comment.

Former President Donald Trump, a Republican who began his re-election campaign in November 2022, last week won endorsements of several Republican lawmakers in Florida. The endorsements are a blow to DeSantis, who has not yet declared his candidacy.

DeSantis met with Netanyahu during a visit to Jerusalem in 2019, calling Florida “the most pro-Israel state in the nation.”

Netanyahu’s plans for judicial reform were paused last month after strikes and mass demonstrations. The proposals would give the government effective control over appointment of Supreme Court judges and allow parliament to overrule many decisions of the court.

When asked on CBS why he would not withdraw the planned reforms, Netanyahu said there was a “broad consensus” to fix the Israeli judicial system.

“I’ve actually said that I will not accept a blanket ability of the parliament to overcome judicial Supreme Court decisions, just as we don’t accept that the Supreme Court can abrogate any decision by the parliament or the government,” he said.
