Threat against US Capitol fizzles, but officials seek 2 more months of National Guard help

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.
