Rep. Jim Himes( D-Conn .) made a spot-on observation about President Donald Trumps frequent Twitter denunciations: They can take aim at nearly everyone except Russian President Vladimir Putin.

Himes, a is part of the House Intelligence Committee, pleaded with FBI Director James Comey on Monday to take notice of Trumps bizarre reluctance to criticize Russias authoritarian leader.

There is intensepublic interest in the fact thatour new chairman will attackanyone and everyone, Himes said. He will attack the castingof Hamilton . He will attack Chuck Schumer. He will attack our allies, Mexico and Germany. He will attackthe intelligence community, whichyou lead, associating you with McCarthyism and Nazism.

Buttheres one person and onecountry which is immune, whichis inoculated from any form ofpresidential attack, Himes continued. No matterwhat the behaviour , no matter iftheres a violation of the INF nuclear treaty , no matterif Vladimir Putin killspolitical opponents the new chairperson defends, obfuscates, does notattack.

Himes addressed Comey during a hearing of the House Intelligence Committee, where the FBI director confirmed the existence of an investigation into possible ties between Trump associates and Russian government officials. Comey said the bureau initiated the probe in July, but declined to theorize on how long it would take to complete.

As you know, our practice is not to corroborate the existence of ongoing investigations, especially those investigations that involve classified matters, Comey told. But in unusual situations, where it is in the public interest, it may be appropriate to do so. This is one of those circumstances.

Himes pointed to a series of odd the linkages between Russia and Trumps surrogates, including Attorney General Jeff Sessions, who recused himself earlier this month from any probe into the 2016 presidential campaign, and retired Lt. Gen. Michael Flynn, who was forced to resign as national security adviser in February after mischaracterizing conversations he had with Russian ambassador Sergey Kislyak.

Without exception, the individuals I quotedhave dissembled or misinformed, maybe even liedabout, the nature of thoseconnections, Himes said, until the politicalpressure has get to a pointwhere they have been fired, orrecused in the case of theattorney general.

Trumps tweets were also the focus of another line of investigation during Mondays hearing, when Comey refuted accusations that former President Barack Obama wiretapped Trump Tower, a claim made by the president on Twitterearlier this month.
