WTF??? Steven Seagal is in Russia "investigating" about the Boston Marathon bombing.

First, there was Dennis Rodman, who struck an unexpected friendship with the reclusive leader of North Korea. Now, add Steven Seagal to the list of improbable celebrity diplomats.

The former action film hero has apparently developed a web of high level contacts in Russia, which he tapped into for a visiting delegation of American lawmakers who came, in part, to investigate April's Boston marathon bombing.

One suspect in that bombing, Tamerlan Tsarnaev, spent six months last year in Dagestan, a restive region in southern Russia.

The meetings, it appears, yielded little new information about the Boston suspect and no smoking gun to suggest an intelligence failure.

"There is nothing specific that could've been done that we can point to that, had it been done differently, would've prevent this," said Rep Dana Rohrabacher, the Republican from California who led the delegation.

But Rohrabacher, who said he has known Seagal for "a number of years" and said the two had often discussed "thwarting radical Islamic terrorism," repeatedly praised the actor for "going out of his way" to set up meetings for the delegation in Russia.
