Former President Donald Trump’s lawyer Sidney Powell criticized U.S. District Judge Linda Parker in a filing Monday asking a federal appeals court to overturn sanctions the judge imposed against the attorney over her failed lawsuit that sought to overturn the 2020 election results in Michigan.

In the 51-page brief, the conservative lawyer and co-counsel Howard Kleinhendler accused Parker, of the Eastern District of Michigan, of having “viewpoint discrimination,” and said her order that required they pay $175,000 in sanctions “bristles with disapproval, disdain and incredulity.”
