Senator Mitch McConnell, the Republican minority leader, said on Sunday that he would vote against the new arms control treaty with Russia, rallying opponents of the pact as it approaches the decisive vote expected this week.
Mr. McConnell, of Kentucky, said the treaty’s verification provisions were inadequate and he worried that it could inhibit development of missile defense despite statements to the contrary by President Obama and the nation’s military leaders. He also criticized Democratic lawmakers for what he said was their cramming the treaty into the final days of the year.
“Rushing it right before Christmas” is just a way of “trying to jam us,” Mr. McConnell said on CNN. “I don’t think this is the best way to be doing this.”
