McCain spoke to more than 100 Republicans in Bloomfield Hills, Mich., urging them to get out the vote for Romney.
“It’s a fiasco and a tragedy and a failure of presidential leadership that resulted in the death of four brave Americans,” he said. “People have said it could be as bad as Watergate, but nobody died in Watergate.”
Campaign spokesman Matt McGrath said McCain was politicizing “a national security tragedy" with his statements about the Libya attack.
"While the president put politics aside to deal with the aftermath of the storm, Sen. McCain doubled down on the Romney campaign's offensive and inaccurate criticism of the president on foreign policy," McGrath said, according to the paper.
Obama has consistently been ahead of Romney in Michigan polls. Although Romney grew up in the Wolverine State, he didn’t support the auto bailout, making Obama more popular in a state with several American car manufacturers.
