A Democratic congresswoman repeated her call to investigate whether President Trump should be impeached.

Representative Maxine Waters (D-Calif.) said on MSNBC that there must be a probe into the unsubstantiated dossier that surfaced last month, alleging that Trump could be subject to blackmail from the Russians.

"The coverage they have on him, [the] sex actions ... that's absolutely true," Waters said, referring to the dossier's detailed description of claims Trump met with Russian prostitutes.

"They should really read it, understand it, analyze it, determine what's fact," she added.

Waters applauded fellow Californian Adam Schiff's (D-Burbank) call for dossier author Christopher Steele to testify before Congress.

Schiff said he will be requesting that Steele, a former spy for the United Kingdom, either come before Congress or meet "in any matter he is comfortable."

"If we do the investigation, then we will find the connections. And I do think that impeachment will be necessary," Waters said.
