WASHINGTON (AP/CBSDFW) – The House Intelligence Committee is issuing subpoenas for several individuals, including former national security adviser Michael Flynn and President Donald Trump’s personal lawyer, Michael Cohen, as part of its investigation into Russian activities during last year’s election.

Subpoenas were approved Wednesday for Flynn and his company, Flynn Intel Group, and Cohen and his firm, Michael D. Cohen & Associates.

According to the Wall Street Journal, the committee also subpoenaed the National Security Agency, the Federal Burea of Investigation and the Central Intelligence Agency for information about what is called “unmasking.”

Reps. Mike Conaway and Adam Schiff, who are leading the committee’s probe, say the panel approved the subpoenas to compel certain individuals to testify and to obtain personal documents and business records. Cohen earlier rejected a House intelligence committee request for information.
