A federal judge in Michigan grilled lawyers for former President Trump Monday over their false claims of fraud in the 2020 presidential election. U.S. District Court Judge Linda V. Parker, who called the claims “fantastical” and “speculative,” is considering whether to ban Sidney Powell, Lin Wood and other Trump allies from practicing law in Michigan, or whether to disbar them altogether.

This comes as The Washington Post reports that the Republican National Committee’s top lawyer warned last November against continuing to push false claims that the presidential election was stolen, calling them a “joke” that could mislead millions of people.
