The Senate parliamentarian ruled Thursday that a fiscal "trigger," important to winning deficit-wary Sen. Bob Corker's support for the GOP plan, will not work under Senate rules. Republican senators are now looking to find new ways to address the concerns of Corker, a so-called deficit hawk Republican from Tennessee.
"It doesn't look like the trigger is going to work, according to the parliamentarian," Senate Majority Whip John Cornyn, R-Texas, told reporters, according to Politico. "So we have an alternative, frankly: a tax increase we don't want to do to try to address Sen. Corker's concerns."
