Roger Stone, former adviser and friend to President Trump, will testify before the House Intelligence Committee Tuesday as part of the investigation into Russian efforts to influence the 2016 presidential election. 

Stone will finally have the opportunity to address several charges of collusion from Democratic lawmakers—notably Reps. Adam Schiff and Jackie Speier—that he did Russian President Vladimir Putin’s “bidding,” “engage[d] with him,” and was even on the Kremlin’s payroll.

“I am most interested in correcting a number of falsehoods, misstatements, and misimpressions regarding allegations of collusion between Donald Trump, Trump associates, the Trump Campaign and the Russian state,” Stone will say in his opening statement provided to the Daily Caller.

“I view this as a political proceeding because a number of members of this Committee have made irresponsible, indisputably, and provably false statements in order to create the impression of collusion with the Russian state without any evidence that would hold up in a US court of law or the court of public opinion.”
