Boebert is the first mother and youngest person to represent that district in Colorado. She has joined an effort against certifying the Electoral College victory of President-elect Joe Biden.

Rep. Doug Lamborn on Monday became the second member of Congress from Colorado to join that effort.

Congress is set to meet in a joint session Wednesday intended to take the final step in certifying Biden’s win following numerous failed court challenges by President Donald Trump’s campaign seeking to undo vote tallies in key states. Biden is set to be inaugurated Jan. 20.

Trump has enlisted support from at least a dozen Republican senators and roughly 100 House Republicans to challenge the vote when Congress considers Biden’s 306-232 win in the Electoral College.

Accepting the Electoral College vote is typically a routine process. But Trump refuses to concede.
