David Axelrod this morning bashed Mitt Romney on "This Week" after the presumptive GOP nominee for president attacked President Obama for his administration's handling of Chinese dissident Chen Guangcheng.

"What's shameful is when presidential candidates are so craven to score political points that they speak irresponsibly on half-information at a time when the president is trying and the administration is trying to resolve a situation that is very very sensitive," said Axelrod, a senior campaign adviser to the president. "It doesn't help to have candidates blunderbussing around trying to score political points."

Romney tweaked the Obama administration earlier this week after Chen was allowed to leave the U.S. Embassy and go to a local hospital, which left him without diplomatic protection.

"If these reports are true, this is a dark day for freedom and it's a day of shame for the Obama Administration," Romney said.

Axelrod also defended President Obama over attacks that he has been "spiking the football" as the nation marks the one year anniversary of the death of Osama bin Laden.

The group, Veterans for a Strong America recently released an advertisement that hit the president for his recent statement affirming his role in the killing of Osama bin Laden.

"It's certainly a legitimate part of his record to talk about," said Axelrod, noting that had the mission gone awry, "the other side would be talking about it and Mitt Romney would be the first one."
