Because they think they can get away with lying.
Unfortunately (or not?) for Rep Loudermilk there is video evidence of what occurred.
...The details: In a letter to Loudermilk, Rep. Bennie Thompson (D-Miss.), the chair of the panel, wrote that Loudermilk has information regarding "a tour you led through parts of the Capitol complex on January 5, 2021," citing a review of evidence in the committee's position.
- - - "Public reporting and witness accounts indicate some individuals and groups engaged in efforts to gather information about the layout of the U.S. Capitol, as well as the House and Senate office buildings, in advance of January 6," Thompson continued
- - - Thompson also claimed the panel has evidence that "directly contradicts" claims by Republicans on the House Administration Committee, of which Loudermilk is a member, that a review of footage determined there were "no tours, no large groups, no one with MAGA hats on" leading up to Jan. 6.
The other side: "A constituent family with young children meeting with their Member of Congress in the House Office Buildings is not a suspicious group or 'reconnaissance tour,'" Loudermilk and Rep. Rodney Davis (R-Ill.), the top Republican on the House Administration Committee, said in a statement.
- - - They said the family never entered the building, accusing the Jan. 6 committee of "pushing a verifiably false narrative" and calling on the Capitol Police to "release the tapes."
- - - They also highlighted an ethics complaint they filed last May against Rep. Mikie Sherrill (D-N.J.) and other House Democrats who made the allegations....
This will be interesting to watch.
Get the popcorn...
