Washington | Democratic members of Congress on Wednesday (Thursday AEDT) accused unnamed Republicans of giving tours of the Capitol to insurrectionists ahead of last week's deadly siege of the Capitol, as federal agencies opened two new investigations into the extent to which Capitol Police and far-right lawmakers were complicit in the mob attack.

The inspector general of the Capitol Police is opening a potentially wide-ranging investigation into security breaches connected to the siege that could determine the extent to which some Capitol Police officers were involved, according to a senior congressional aide with direct knowledge of the investigation. The inspector general will suspend all other projects until the investigation is complete, the aide said.
