What’s Paul Ryan’s role during fiscal-cliff negotiations?

The day after the election, House Speaker John Boehner, the man now at the center of the negotiations with President Obama, called Ryan, according to a Boehner aide, because the speaker wanted “to make sure he was in the fold from Day One,” adding he’s been a “close part of the thought process.”

And an aide to Ryan, who asked that his name not be used, says the role of the Wisconsin congressman is as a “resource to the speaker, a resource to House Republicans.”

“He has responsibilities as the House budget chairman, he has responsibilities to the first district of Wisconsin. He needed to be where the fight is,” added the aide. Nevertheless he wants to be “deferential” to those leading the conversation — namely Boehner, House Majority Leader Eric Cantor and Majority Whip Kevin McCarthy.
