Grassley clearly took offense on Sunday to Obama calling for swift movement on the reform bills, tweeting that Obama has "got nerve" to make such a demand while he was traveling in Europe.

Last Sunday, Grassley tweeted:
Pres Obama you got nerve while u sightseeing in Paris to tell us"time to deliver" on health care. We still on skedul/even workinWKEND.

Pres Obama while u sightseeing in Paris u said 'time to delivr on healthcare' When you are a "hammer" u think evrything is NAIL I'm no NAIL

On Tuesday, Grassley said that he didn't object to Obama taking a vacation but he didn't like Obama's suggestion that "Congress is dragging its heels on healthcare reform."
