The House Democrat who will head the Judiciary Committee warned President Donald Trump’s “evading accountability is coming to an end” — saying his 2016 business dealings in Russia gave Moscow “leverage” over him.

In an interview with NBC News’ “Meet The Press,” Rep. Jerrold Nadler, D-N.Y., charged “we have a president who lies incessantly to the American people about big matters and small matters, who surrounds himself with people who lie incessantly to the American people.”

“The key fact now is that the time that he can get away with lying to the American people all the time and evading accountability is coming to an end.”

Nadler said Russia has “leverage” over Trump because of his 2016 dealings on a proposed Trump Tower Moscow.

"The fact that he was lying to the American people about doing business in Russia and the Kremlin knew he was lying gave the Kremlin a hold over him," Nadler said.

"One question we have now is, does the Kremlin still have a hold over him because of other lies that they know about?"

“The question has always been why was the president was so obsequious to [Russia President Vladimir] Putin from the beginning of the campaign up to the present day,” Nadler added. “It may be that it's because the Kremlin has leverage over the president, which is a terrible thing, if true.”

Nadler said the alleged leverage is why there needs to be legislation to protect special counsel Robert Mueller’s investigation of Russia meddling in the 2016 election.

“We are dependent on that investigation to get to the bottom of the corruption in the campaign, of the Russian role in the campaign, in the Trump campaign, the president's role in colluding with the Russians if he did,” Nadler said. “We know his campaign did. The question is did he personally. So we have to do whatever we can to protect that investigation.”
