Leading House Democrats told Politico for a report published Saturday they are consulting with House General Counsel Douglas Letter on how to compel President Trump or his administration to reveal the content of his one-on-one meetings with Russia President Vladimir Putin.

"I had a meeting with the general counsel to discuss this and determine the best way to find out what took place in those private meetings — whether it's by seeking the interpreter's testimony, the interpreter's notes, or other means," said Rep. Adam Schiff (D-Calif.), who serves as House Intelligence Committee chair.

Rep. Eliot Engel (D-N.Y.), chair of the Foreign Affairs Committee, is working with Schiff. "I'm not saying that I'm in favor of interpreters turning over all their notes, but I do think that it shouldn't be up to the president to hide the notes," Engel told Politico.

Of particular interest is Trump's private conference with Putin in Helsinki last summer, where the two presidents met alone with their respective interpreters for 90 minutes. At the press conference following the talks, Trump said he didn't "know any reason why it would be" Russia which sought to meddle in the 2016 election, contradicting the assessment of U.S. intelligence agencies.

Last month, The Washington Post reported Trump has "gone to extraordinary lengths" to hide details of his conversations with Putin, including from his own administration. In one case, Trump reportedly took his interpreter's notes from a call with Putin and told the interpreter not to discuss the talk with other officials. Bonnie Kristian
