Senator Ben Cardin: 'We know that this involves Russia'
Ben Cardin, who sits on the Senate Foreign Relations Committee, tells BBC News that an independent commission of inquiry into links between the Trump campaign and Russia should be established.
"We know that this involves Russia," he said of the firing of FBI director James Comey, despite the White House saying the decision was made over his handling of Hillary Clinton's emails.
