Police said Wednesday they have bolstered security in Washington after intelligence uncovered a "possible plot to breach the Capitol" on March 4, a day that holds significance for conspiracy-believing supporters of former president Donald Trump. "We have obtained intelligence that shows a possible plot to breach the Capitol by an identified militia group on Thursday, March 4," the US Capitol Police said in a statement on Twitter, nearly two months after a deadly riot by Trump supporters shook the citadel of American democracy. "We have already made significant security upgrades to include establishing a physical structure and increasing manpower to ensure the protection of Congress, the public and our police officers," the police force added. mlm/jm
