WASHINGTON - A House committee tasked with investigating the Jan. 6 Capitol insurrection is moving swiftly Tuesday to hold at least one of Donald Trump's allies in contempt as the former president is pushing back on the probe in a new lawsuit.Trump is aggressively trying to block the committee's work by directing former White House aide Steve Bannon not to answer questions in the probe while also suing the panel to try to prevent Congress from obtaining former White House documents.
