In the continuing quest to lay everything bare, as it pertains to Trump, his associates, and anything Russia-related, the Senate Intelligence Committee has requested information from the Treasury Department’s financial crimes unit on President Trump and his top aides.

“We’ve made a request, to FinCEN in the Treasury Department, to make sure, not just for example vis-a-vis the president, but just overall our effort to try to follow the intel no matter where it leads,” Sen. Mark Warner (Va.), the panel’s top Democrat, told CNN.

“You get materials that show if there have been, what level of financial ties between, I mean some of the stuff, some of the Trump-related officials, Trump campaign-related officials and other officials and where those dollars flow — not necessarily from Russia.”

Warner is working with committee chairman, Richard Burr (R-N.C.) to obtain that information, as part of the broader investigation into Russian interference in the 2016 election.

Warner has also vowed to block Sigal Mandelker, Trump’s nominee for the Treasury Department’s undersecretary for terrorism and financial intelligence, until they cooperate by providing the requested information.

“Chairman Burr and I requested that information. Until we get it, I’m not going to support the administration’s nominee for undersecretary of Treasury finance, for terrorism and finance, because they owe us these documents first,” Warner said.

The Intelligence Committee also sent requests to four former Trump campaign associates on Friday asking them to turn over emails and other records of communication with Russians.

Where this eventually leads remains to be seen.

The Senate Intelligence Committee is one of several committees looking into potential meddling by Russia in the 2016 election, as well as any possible connections between the Trump campaign team and Moscow.
