Brendan Buck, BoehnerJohn Andrew BoehnerFormer top Treasury official to head private equity group GOP strategist Steve Schmidt denounces party, will vote for Democrats Zeal, this time from the center MORE’s press secretary, initially tweeted a link to a blog post on the Speaker’s website listing quotes from House Democrats who said they support spending cuts. Buck called them “hostage takers” in his tweet.

Jon Lovett, who previously wrote Obama’s White House speeches for three years, tweeted back.

“How about 2010 when Dems extracted concessions from the president for a debt limit increase? Wrong then?” Buck replied.

There’s nothing wrong, Lovett said, with negotiating a deal as part of a limit increase. It’s wrong, however, to use “limit and default threat as leverage.”

House and Senate lawmakers are about a week away from the debt ceiling deadline — when the federal government could no longer borrow money. If Congress doesn’t raise the ceiling, the nation would default.

President Obama has reiterated the debt limit must be increased, and he won’t cave to GOP demands. He has invited various congressional caucuses of both parties to the White House to discuss how to avert a crisis.

If Obama compromised with Republicans like he did three years ago, there’d be no issue, Buck said.
