New York Times columnist Nicholas Kristof responded to the explosions that blasted the Boston Marathon on Monday with an eyebrow-raising comment about Republicans on Capitol Hill.

In a tweet during the aftermath of the apparent attacks, Kristof wrote, “Explosion is a reminder that ATF needs a director. Shame on Senate Republicans for blocking apptment.”

The columnist linked to a Feb. 1 article in the Washington Post about Republicans not supporting President Obama’s nominee to lead the Alcohol, Tobacco, Firearms and Explosives bureau.

Early reports from authorities indicate two bombs exploded near the finish of the Boston Marathon on Monday, killing at least two people and injuring more than 20.

Update: Kristof recanted his comment, calling it a “low blow” after being criticized: “People jumping on me for criticizing Sen Repubs for blocking ATF appointments. ok, that was low blow. i take it back,” he tweeted.
