Former White House Chief of Staff Mark Meadows and Donald Trump.SAUL LOEB/AFP via Getty Images; Dave Sanders-Pool/Getty ImagesMark Meadows has requested Supreme Court to recognize immunity for president's subordinates.He's criminally charged alongside Trump for a plot to erase Biden's electoral win in Georgia.One of Trump's own Supreme Court appointees seemed to draw the opposite conclusion.Before the Supreme Court heard oral arguments in former President Donald Trump's immunity case, Mark Meadows tried to get his foot in the door.The high court had agreed to decide whether former presidents can enjoy legal immunity from criminal charges for actions taken during their presidency.Trump hoped that a decision would scuttle the indictment against him over his attempts to overturn the 2020 presidential election — a result that now seems unlikely, even though the trial will likely be delayed until after the 2024 presidential election.Meadows, a former Republican member of Congress, served as Trump's chief of staff in the final year of his White House administration.
