House Democrats Rep. Maxine Waters, D-California, and Rep. Jerrold Nadler, D-New York, argued Special Counsel Robert Mueller's investigation into Russian meddling in the presidential election should be allowed to continue.

"We are here today on behalf of at least 171 members of Congress who believe Special Counsel Mueller is doing a great job," Waters said, at a news conference Thursday, surrounded by about 12 other House Democrats. "We are here today on behalf of at least 171 members Congress who believe Mr. Mueller's investigation should and must continue and must not be obstructed."

Mueller is responsible for the special counsel investigation into Russian meddling in the 2016 presidential election and any connections between President Trump's campaign and the Kremlin.

Thom Tillis, R-North Carolina, and Lindsey Graham, R-South Carolina, is intended to protect Mueller-- also a Republican-- as he and his team work on the investigation.
