Though Burr and Mark Warner, the committee’s Democratic vice-chairman, have largely agreed on the parameters of the investigation, they have recently begun to disagree more publicly on what the facts they’ve collected add up to: Conspiracy? A series of coincidences and bad decisions? Or something in between?

The new Democratic chair of the House Intelligence Committee, Adam Schiff, does not believe those questions can be answered without a thorough examination of Trump’s financial history and his potential entanglements with Russian money launderers, especially given new revelations about Trump’s efforts to pursue a multimillion-dollar real-estate deal in Moscow in 2016. So he has revived the panel’s floundering Russia probe by hiring upwards of a dozen dedicated staffers with expertise in corruption or illicit finance, or prosecutorial experience. That brings the total number of majority staffers, which could increase, to 24 on the House panel.* Many are bringing specific skills to the committee that the nine staffers working on the Senate’s Russia probe—despite their extensive intelligence-community experience—do not have, according to two people with direct knowledge of that committee’s work.

The reinvigorated House probe intends to pursue avenues of inquiry that may have been overlooked by the Republican-led House Intelligence Committee investigation, including the substance of Trump’s closed-door conversations with Russian President Vladimir Putin over the past two years. A particular emphasis will also be placed on Deutsche Bank—the Trump family’s bank of choice for decades, which was fined in 2017 over a $10 billion Russian money-laundering scheme involving its Moscow, New York, and London branches. “The concern about Deutsche Bank is that they have a history of laundering Russian money,” Schiff told NBC in December. “This, apparently, was the one bank that was willing to do business with the Trump Organization. If this is a form of compromise, it needs to be exposed.” Deutsche Bank representatives said last month that the bank was working with the House Intelligence and Financial Services Committees to “determine the best and most appropriate way of assisting them in their official oversight functions.”

Special Counsel Robert Mueller is pursuing a separate federal investigation into a potential conspiracy between the campaign and Russia in 2016. While he can issue indictments, the congressional committees can pursue a broader inquiry assessing misconduct that may not rise to the level of criminal activity.

It is undeniable that the Senate Intelligence Committee has traditionally been far more unified than its House counterpart, mostly by virtue of longer term limits and different rules. The committee produced important bipartisan reports over the past two years, including one last July that reaffirmed the intelligence community’s assessment that Russia worked to harm Hillary Clinton’s candidacy in 2016, and another that provided a sweeping analysis of Russia’s ongoing disinformation campaigns. The panel has also interviewed more than 200 witnesses and sifted through hundreds of thousands of pages of documents.
