Senate GOP leadership reaffirmed its commitment to voting on a bill to build the Keystone XL pipeline during a weekly news conference Wednesday, adding that President Barack Obama’s veto threat on Keystone legislation could give someone “whiplash.” “It seems with every new day, we have a new veto threat from the president,” Majority Leader Mitch McConnell said. “I think it’s interesting to note, this is exactly the same bill that was before the Senate last month, when the then-majority was trying to save Sen. [Mary L.] Landrieu in a runoff, and I don’t recall the president mentioning at that point he would veto the bill.”
