During FBI agent Peter Strzok's testimony on Capitol Hill on Thursday, Rep. Elijah Cummings (D-Md.) highlighted the number of guilty pleas and indictments secured by Special Counsel Robert Mueller.

Cummings, the top Democrat on the House Oversight Committee, pointed out that Republican lawmakers had promised they would not interfere in Mueller's investigation.

He accused them of changing course once Mueller starting making significant headway, including guilty pleas from Trump campaign officials.

As he spoke, Democratic staffers then held up five large posters showing the three Trump campaign officials - including Michael Flynn and Rick Gates - and two campaign associates who have pleaded guilty to charges in the special counsel's probe.

House Judiciary Committee Chairman Bob Goodlatte (R-Va.) interrupted and questioned if the posters were appropriate.

When Cummings and other Democratic lawmakers asked Goodlatte to cite a rule to justify his objection, he was unable to do so and Cummings continued.

“Let me underscore, these are not allegations — these are admissions,” Cummings said, noting that Mueller has also indicted 18 other individuals.
