Committee ranking member Rep. Adam Schiff (D-CA) speaks during a hearing before the House (Select) Intelligence Committee November 1, 2017 on Capitol Hill in Washington, DC.

Four Democrats will join the House Intelligence Committee as the panel resuscitates its inquiry into President Donald Trump's ties to Russia under a new Democratic majority and new chairman Adam Schiff.

Reps. Val Demings of Florida, Raja Krishnamoorthi of Illinois, Sean Maloney of New York and Peter Welch of Vermont will serve on the committee, House Speaker Nancy Pelosi said Wednesday.

The committee pursued a limited investigation into Russian interference in the 2016 election under Chairman Devin Nunes, R-Calif.

Under Republican leadership, Democrats' efforts to pursue their own lines of inquiry were largely stymied. The committee cleared the president and his associates of wrongdoing and criticized the intelligence community for "significant intelligence tradecraft failings."

Schiff said at the time that the report signed by the committee's Republicans reached flawed conclusions and was based on politics. In a statement Wednesday, the California Democrat said he looked forward to working with the new members "to restore regular order and comity" on the powerful select committee.

A representative declined to comment about Schiff's plans for pursuing the Russia investigation. But the committee has reportedly made several recent hires, including an expert in corruption and illicit finance, in line with its plans to pursue the matter.

"There's a lot of work yet to be done on Russia," a senior committee official was quoted telling CBS News in a story published Tuesday. "What we're doing is we are creating a purpose-built team that will take the point on that."

Schiff said ahead of the midterm elections that Republicans had dropped the inquiry but Democrats had continued. In an interview with CNN in October, he said that "work won't stop when we take the majority."

"We will be able to get answers the Republicans were unwilling to pursue. Records that the Republicans wouldn't ask for," he said.

Correction: This story was revised to correct that Rep. Peter Welch represents Vermont.
