The tradition is in doubt this year, when President Donald Trump has vowed not to attend Joe Biden’s inauguration and has pushed the baseless claim that the election was stolen.
The Republican former Ohio congressman began his remarks during a webinar on health care policy Monday by talking about Trump's baseless claims of widespread election fraud and last week's siege of the Capitol by pro-Trump insurrectionists.
His former chief of staff Mick Mulvaney tweeted: 'The President’s tweet is not enough. He can stop this now and needs to do exactly that. Tell these folks to go home.'
Trump has claimed widespread election fraud, but a series of court challenges on his behalf have been unsuccessful in overturning the election results.
