Sekulow originally denied that Trump had fallen under investigation, but later appeared to reverse that assertion, saying that "he's being investigated for taking the action that the attorney general and deputy attorney general recommending him to take."

"You've now said that he is being investigated," Wallace said. "You just said, sir, you just said that he's being investigated."

"Let me be crystal clear so you completely understand, we have not received, nor are we aware of any investigation of the president of the United States. Period," Sekulow responded.

When Wallace pressed him on the apparent contradictions in his statements, Sekulow insisted that he had been clear that the president was not under investigation, and accused the Fox News host of "putting words in my mouth."

"I do not appreciate you putting words in my mouth, when I've been crystal clear that the president is not and has not been under investigation," Sekulow said.

Wallace joked that Sekulow seemed not to know whether the president was being probed or not.

"Well, you don't know that he's not under investigation, again sir," Wallace said.

"You're right, Chris, I can't read the mind of the special prosecutor," Sekulow responded.

"Okay, well good, we're in agreement," Wallace replied. "You don't know whether he's under investigation or not."

The Washington Post reported last Wednesday that Mueller's investigation into Russia's role in the 2016 election had expanded to include of probe of Trump himself for allegedly attempting to obstruct justice.
