The Republican whip, from Louisiana

“I agree with the House Intelligence Committee's report concluding that there is no evidence of collusion between the Trump campaign and the Russian government in the 2016 election, and I think there are credibility concerns the Mueller investigation needs to address so they can dispel the fears that this is becoming a partisan witch hunt.

“The credibility of the Mueller investigation will be in doubt unless we get to the bottom of the many serious questions regarding the F.B.I.'s handling of their investigation of the Trump campaign, as well as their investigation into Hillary Clinton's negligent transmission of classified material over her unauthorized email server. That's why I agree with the many others who have called for the appointment of an additional special counsel who, unlike Mueller, has the authority to look into the potential abuses of the FISA system that allowed the Democrat-funded Steele dossier to serve as the basis for the initial F.B.I. investigation.

“The addition of an outside special counsel will ensure our ability to have full faith in our investigations into the very serious threats Putin's rogue government poses to our elections and nation as a whole.”
