We all know the Republican Party, aided by right wing blogs and media (as always), will now engage in an orgy of recriminations and second-guessing, trying every possible way to use the Boston terror attack against the Obama administration.

We know this because it’s what they do. And the first line of attack will be that President Obama ignored warning signs about the Tsarnaev brothers. The crazier right wingers are already spinning this into conspiracy theories, suggesting (or saying outright) that Obama sympathized with the terrorists and helped them carry out their plot.

But there’s already a monkey wrench in their toxic conspiracy soup, because Russia has informed the US that Tamerlan Tsarnaev did not contact terror groups during his trip to Russia in 2012.

WASHINGTON — Russia has informed the United States that it knew of no contact between Tamerlan Tsarnaev and any known terrorist groups during his six-month trip to Dagestan in 2012, according to an official who attended a closed-door Senate briefing Thursday morning by top counterterrorism officials.

Russia provided the information to US authorities five days ago, the official said.

The statements could bolster theories that Tsarnaev and his younger brother, Dzhokhar Tsarnaev, were acting on their own when they allegedly planted two bombs near the finish line of the Boston Marathon on April 15, and not at the behest of any foreign terror groups.
