President Trump's personal attorney Michael Cohen told CNN in May that he was declining invites to testify from the House & Senate intelligence committees, which are pursuing investigations into Russia's suspected efforts to influence last year's election & any potential involvement by the Trump campaign.

BuzzFeed News first reported Cohen would speak to the Senate panel Tuesday.

Cohen drew further scrutiny in recent weeks when it came to light that he reached out to the Russian government about a potential Trump Tower in Moscow while Trump's campaign for the presidency was well in progress.

Cohen was subpoenaed by the House intelligence committee, & his lawyer provided documents to that panel for its Russia investigation.
