Lieu: Trump on Russia investigation ‘has all the markings of Watergate’

Rep. Ted Lieu (D-Calif.) said Wednesday that President TrumpDonald John TrumpLieu: There will be 'widespread civil unrest' if Trump fires Mueller Attorneys for Trump, Mueller hold face-to-face meeting to discuss potential interview topics: report Trump tariffs not helpful for nuclear talks, South Korea says MORE's lack of action on the issue of Russia's election meddling closely resembled the Watergate scandal during the Nixon administration. 

"This has all the markings of Watergate where you have a person acting not only to obstruct an investigation but also taking actions that are inconsistent with what an innocent person would do," Lieu told MSNBC's Ari Melber. 

"As we sit here today, the president still has not imposed bipartisan congressional sanctions on Russia. He still has refused to condemn the Kremlin or [Russian President] Vladimir Putin for their attack on American elections in 2016, and he still has refused to order the NSA or FBI to stop an attack in the future," he continued. 

U.S. Cyber Command chief Adm. Michael Rogers, who also serves as the head of the NSA, told the Senate Intelligence Committee on Tuesday that he has not received an order from the Trump administration to stop Russian cyberattacks targeting U.S. elections.

FBI Director Christopher Wray has also said he has not received direction from Trump to combat Russia election meddling. 

The developments come as special counsel Robert MuellerRobert Swan MuellerSasse: US should applaud choice of Mueller to lead Russia probe MORE continues to probe alleged ties between the Trump campaign and Russia's election meddling. His investigation is rumored to include possible obstruction of justice charges against the president.

Trump has repeatedly denied any collusion between his campaign and the Kremlin, calling the probe a "witch hunt."

Watergate refers to a scandal that eventually resulted in former President Nixon's resignation.
