Rep. Elijah Cummings (D-Md.) suggested Sunday that more than one person at the White House may be under investigation for having ties to Russia.

“My impression, when I walked out of the briefing, was that this thing runs deep,” Cummings told George Stephanopoulos on ABC’s “This Week,” speaking about a closed-door briefing lawmakers received last week on the matter. “There may be quite a few people that may have some problems with the law.”

The Washington Post reported last week that the federal investigation into possible ties between President Trump’s campaign and Russia now includes a current White House official as a “significant person of interest.”

The House Intelligence Committee has asked a former Trump campaign staffer who has ties to Russia to voluntarily sit for an interview and submit documents for its investigation, The New York Times reported Saturday.

As the investigations have ramped up, several Democratic lawmakers have publicly called for Trump’s impeachment, but Cummings warned against focusing on that at this time.

“Impeachment is one, but we’ve got to concentrate on the fact that the Russians interfered with our elections,” Cummings said. “I keep telling people, don’t get so caught up in impeachment that you forget about that.”

Deputy Attorney General Rod Rosenstein briefed House lawmakers Friday on the investigation into Russia’s actions in the presidential election and possible ties to the Trump administration.
