Rep. Justin Amash (R-Mich.) is criticizing both Democrats and Republicans for trying to pass off blame for looming automatic cuts.

For weeks, Republicans have sought to blame the sequester on President Obama. In floor speeches, leaders call it "President Obama's sequester." On social media, they have used the hashtag #Obamaquester and highlighted a passage from Bob Woodward's book about the 2011 debt ceiling crisis that shows the idea originating in the White House.

Amash thinks it's weak. "It's totally disingenuous," he told BuzzFeed. "The debt ceiling deal in 2011 was agreed to by Republicans and Democrats, and regardless of who came up with the sequester, they all voted for it. So, you can't vote for something and, with a straight face, go blame the other guy for its existence in law." (He also called the hashtag strategy "kind of 2008.")

White House spokesman Jay Carney seized on Amash's words. But Amash shot back, arguing that Obama is being equally insincere.

When Carney responded that the point of the sequester was to be so awful that Congress would find another way to reduce the deficit, Amash was incredulous.

Amash, a savvy user of social media, recently called out Sen. John McCain (R-Ariz.) on Twitter, labeling a joke the senator made about Iranian President Mahmoud Ahmadinejad "racist."
