(CNN) - John Sununu, a top surrogate for Mitt Romney’s presidential campaign, said Thursday that Colin Powell’s repeat endorsement of President Barack Obama could be explained partly by the two men’s shared race.
Speaking on CNN’s “Piers Morgan Tonight,” Sununu downplayed the importance of the former secretary of state’s endorsement, pointing to the support Romney’s received from former President George H.W. Bush. He went on to explain that Powell’s endorsement of Obama didn’t rely solely on the political issues at hand.
"When you take a look at Colin Powell, you have to look at whether that's an endorsement based on issues or he's got a slightly different reason for endorsing President Obama," Sununu said, adding: "I think when you have somebody of your own race that you're proud of being president of the United States, I applaud Colin for standing with him."
Later, Sununu released a statement saying "Colin Powell is a friend and I respect the endorsement decision he made and I do not doubt that it was based on anything but his support of the President's policies."
Sununu also pointed to Morgan's original question, which was whether Powell should leave the Republican Party.
"I don't think he should," Sununu wrote.
Powell, who served as the first African American secretary of state under President George W. Bush, made his endorsement earlier Thursday, citing a number of issues not related to race as reasons he was backing Obama for a second time.
The Republican said he believe the economy is "starting to pick up" and attributed the recovery to the president's polices, citing specifically the auto industry bailout and Obama's economic proposals. "Generally we've come out of the dive and we're starting to gain altitude," he said.
Powell said he was "uncomfortable" with Romney's tax plans and views on foreign policy. Pointing to Monday night's final presidential debate, Powell argued the GOP nominee had changed positions on the wars in Afghanistan and Iraq. The former secretary of state said he was concerned with the advice Romney was getting from campaign staff.
"I think there are some very, very strong neo-conservative views that are presented by the governor that I have some trouble with," Powell said, though he did not elaborate on which views.
"I also saw the president get us out of one war, start to get us out of a second war and did not get us into any new wars," he said.
Powell made headlines when the former George W. Bush administration official, who also worked for President Ronald Reagan and President George H.W. Bush, crossed party lines and supported Obama last cycle.
