Lewandowski was the final witness in the committee’s probe into Russian interference, and appeared in front of the committee for the second time last month.
During his first interview in March, Lewandowski reportedly refused to answer questions related to things that happened after he left the campaign in June of 2016. His latest appearance seemed to be more of the same, as he reportedly swore at Democrats and told them he would only answer "relevant" questions.
"I’m not answering your fucking question," he apparently shouted at one point.
Lewandowski did not deny he used rough language and blamed Democrats for using expletives first.
"I had to repeat on multiple occasions that there was no collusion, cooperation or coordination because the Democrats couldn’t understand my plain English way of speaking," Lewandowski told CNN. "The language they used in the committee was appalling. I’ve never heard such language used before."
"I felt the need to respond in kind," he said.
