Senate Republicans warned on Thursday that they will block any efforts to expand the Supreme Court, and they urged the justices not to be "cowed" by a recent legal brief from Senate Democrats calling on them to reject a gun case.

"Our colleagues ... openly threatened this Court with political retribution if it failed to dismiss the petition as moot," the GOP senators wrote in their letter to the Supreme Court's clerk. "The implication is as plain as day: Dismiss this case, or we’ll pack the Court."
The Democrats' brief urged the Supreme Court not to take up a challenge to New York City's gun laws, writing that the courts "do not undertake political 'projects.' Or at least they should not."
Progressives praised the brief and viewed it as a warning shot to the court to change tactics or face growing calls for structural reforms.
Brian Fallon, the executive director of Demand Justice — a progressive group that has floated expanding the number of Supreme Court justices — called the brief a "badass move."
ThinkProgress, which is affiliated with the left-leaning Center for American Progress Action Fund, characterized the Democratic senators as declaring "all-out war" on the Supreme Court.

Senate Republicans, in their letter, argued that the brief was the latest example of the independence of the courts being "under assault."
The courts have emerged as a lightening rod issue during the Trump era. Progressive groups have tried to make structural reforms like expanding the Supreme Court a litmus test for 2020 Democratic presidential candidates.

Republicans have set a record pace on influential appeals court nominees, and GOP senators nixed the 60-vote filibuster for Supreme Court nominees in 2017. Democrats had already removed the same vote threshold for lower court and executive nominees in 2013.
"The Democrats’ amicus brief demonstrates that their court-packing plans are more than mere pandering. They are a direct, immediate threat to the independence of the judiciary and the rights of all Americans," Republicans wrote in their letter.
"For our part, we promise this: While we remain Members of this body, the Democrats’ threat to 'restructure' the Court is an empty one. We share Justice [Ruth Bader] Ginsburg’s view that 'nine seems to be a good number.' And it will remain that way as long as we are here," they added.
