National Guard troops keep watch at the Supreme Court on Capitol Hill in Washington, early Thursday, March 4, 2021, amid intelligence warnings that there is a “possible plot” by a group of militia extremists to take control of the Capitol on March 4 to remove Democrats from power. The threat comes nearly two months after thousands of supporters of then-President Donald Trump stormed the Capitol in a violent insurrection as Congress was voting to certify Joe Biden’s electoral win.
