House Intelligence Committee Chair Devin Nunes said that Paul Manafort, President Donald Trump’s former campaign chairman, has volunteered to testify before his committee, which is investigating alleged ties between Trump campaign officials and Russia as well as the Kremlin’s activities in the 2016 election.

Nunes made the announcement on Friday morning, adding that the committee had also asked FBI Director James Comey and NSA head Adm. Michael Rogers to return and brief the panel.

Comey appeared before the House Intelligence Committee on Monday and confirmed the bureau was probing Russia’s role in the elections – as well as Trump aides’ possible ties to the Kremlin.

Nunes’ announcement that Manafort, through his lawyer, offered to speak to the committee followed a controversial week in which the California Republican lawmaker personally briefed President Trump about new revelations he said potentially demonstrate that Trump and his campaign aides may have been swept up in legal surveillance activities by the intelligence community during the presidential transition period.
