"Schiff should be Impeached, and worse!" he added.

Can you believe that Shifty Adam Schiff, the biggest leaker in D.C., and a corrupt politician, is upset that we didn’t inform him before we raided and killed the #1 terrorist in the WORLD!?

Trump frequently goes after Schiff, whose panel, in addition to the House Foreign Affairs and House Oversight and Reform committees, is investigating the president's dealings with Ukraine. The inquiry was launched last month after revelations that Trump had pushed Ukrainian President Volodymyr Zelensky to look into former Vice President Joe Biden Joe BidenFormer Pence aide: White House staffers discussed Trump refusing to leave office Progressive group buys domain name of Trump's No. 1 Supreme Court pick Bloomberg rolls out M ad buy to boost Biden in Florida MORE, a leading Democratic presidential candidate, and Biden's son.

While discussing a rough transcript of the Trump-Zelensky call, Schiff paraphrased at certain points, saying Trump told the foreign leader to “make up dirt on my political opponent.”

His comment sparked criticism from Republicans, and a resolution, which has since failed, was introduced to censure him.

Schiff has defended his comments, calling them partially a parody.

"My summary of the president’s call was meant to be, at least part, in parody. The fact that that’s not clear is a separate problem in and of itself," he said last month.

"Of course, the president never said, ‘If you don’t understand me I’m going to say it seven more times,’ my point is, that’s the message that the Ukraine president was receiving in not so many words," he added.

Trump announced Sunday that ISIS leader Abu Bakr al-Baghdadi had been killed in a U.S. military raid and said he did not inform congressional leadership over a fear of leaks.
