The top Democrat on the Senate Intelligence Committee says reporters should, “stay tuned” to see what action panel Democrats might take to ensure the integrity of an investigation led by Chairman Richard M. Burr after reported contact with the White House.

Reports of a conversation between the Trump White House and the North Carolina Republican have cast a chill over the panel’s probe of alleged Russian efforts to undermine the 2016 U.S. election.

Democratic members of the Intelligence Committee huddled late Monday in a secure facility within the Capitol Visitor Center, departing for a sequence of late nomination votes.

Asked following the meeting about what the panel’s Democratic membership could do to ensure Burr maintains the integrity of the investigation, Warner said the media should keep watch.

Sen. Ron Wyden, D-Ore., a longtime Intelligence Committee member, said after the floor votes that he feared conversations with White House officials by Burr could prompt questions about the panel’s independence.
