The former president urged the justices to move slowly in his federal election interference case, an apparent attempt to delay the trial, set for March.
The former White House chief of staff, a key witness to Donald J. Trump’s efforts to remain in power after his 2020 election loss, maneuvered to provide federal prosecutors only what he had to.
The appeal seeks to narrow the scope of testimony that former Vice President Mike Pence can provide the grand jury investigating former President Donald Trump’s efforts to stay in power.
The ruling paves the way for testimony from Mark Meadows and others. Separately, a Trump lawyer appeared before a grand jury looking into the former president’s handling of classified documents.
