Included on the list are current and former associates of President Donald Trump believed to have been in contact with Russian officials during the campaign or transition period. According to CNN's Anderson Cooper, the list includes Jared Kushner, Trump's son-in-law and senior adviser; Roger Stone, a Trump confidant; Michael Flynn, the former national security adviser; and Carter Page, an early Trump campaign adviser.

The committee's ranking Democrat, Rep. Adam Schiff, declined to comment. A spokesman for Rep. Mike Conaway, who is leading the investigation, also declined to comment.

The committee's probe into Russia's election-related meddling, and whether anyone from the Trump campaign worked to collude with Moscow to undermine Hillary Clinton's candidacy, stalled last month amid questions about the ability of the committee's chairman, Devin Nunes, to lead an unbiased investigation.

Nunes stepped aside from the probe earlier this month and handed it over to Conaway, which appears to have broken the partisan impasse that had plagued the committee for most of March.

Last week, the committee released a statement saying it had invited three former officials with knowledge of Russia's interference — former Deputy Attorney General Sally Yates, former CIA Director John Brennan, and former Director of National Intelligence James Clapper — to testify in an open hearing in May. That hearing was originally planned for late March, but Nunes unexpectedly scrapped it.

The committee also invited FBI Director James Comey and National Security Agency Director Adm. Mike Rogers to appear at a closed hearing on May 2.

The full committee has also now gained access to the classified intelligence documents Nunes said he obtained from a source on White House grounds last month, according to CNN. Nunes sparked bipartisan outcry and came under intense scrutiny when he briefed Trump on the documents directly without first sharing them with Schiff.

Reports have said Nunes obtained those documents from White House officials — despite Nunes' earlier claims that he got them from an intelligence source — fueling speculation that administration officials had orchestrated the stunt to distract the press from Comey's revelation that the FBI was investigating whether various Trump associates had ties to Russia.

"We also are now having made available to us documents that were not heretofore available to us before," Democratic Rep. Denny Heck told CNN. "So every indication is that we are now leaning into this. And I think [Conaway] ought to be given the space to do the right thing."

As the House gets back on track, the Senate Select Intelligence Committee's investigation into Trump's ties to Russia has stalled amid partisan bickering and staffing problems, according to multiple reports published earlier this week.

On Wednesday, the committee hired the former head of intelligence law at the National Security Agency, April Doss, to work with it as it examines "allegations that Russia participated in a disinformation campaign intended to benefit President Donald Trump, and claims of potential collusion between the Trump campaign and Russia," Doss' law firm said in a press release.
