Story highlights House intel panel issued subpoenas in Russia investigation

The subpoenas come a day after Cohen said he would not cooperate with congressional investigators

Washington (CNN) The House intelligence committee issued subpoenas Wednesday to former national security adviser Michael Flynn and President Donald Trump's personal lawyer, Michael Cohen, as part of the probe into Russian activity during the 2016 election.

The panel also issued subpoenas for documents related to "unmasking" of names separate to the Russia investigation.

The subpoenas, the first from the House panel, seek their testimony, as well as documents from their businesses. The committee issued a total of seven subpoenas Wednesday -- four related to the Russia investigation and three seeking details of "unmasking" of US residents by former national security adviser Susan Rice, former CIA Director John Brennan and former US ambassador to the United Nations Samantha Power, a source said Wednesday.

"As part of our ongoing investigation into Russian active measures during the 2016 campaign, today we approved subpoenas for several individuals for testimony, personal documents and business records," Reps. Michael Conaway, R-Texas, and Adam Schiff, D-California -- the co-leaders of the House investigation -- said Wednesday in a statement.

"We hope and expect that anyone called to testify or provide documents will comply with that request, so that we may gain all the information within the scope of our investigation. We will continue to pursue this investigation wherever the facts may lead," they added.
