He is a frequent guest on the national Sunday talk shows, usually defending the Obama administration's policies.
So it was a bit awkward to see Obama forget O'Malley's name at an education event Monday. Sure there are 50 governors to keep track of, but O'Malley -- the chairman of the Democratic Governors Association -- has a higher profile in Washington than many, if not most of them.
Highlighting Maryland education polices, Obama called out what he thought was the governor's name, according to a pool report of the event. "Jack O'Malley, where is he?" the president said.
"I mean, Martin.”
O'Malley seemed to take the moment in stride and even got in a plug for his youngest son, 9-year-old Jack.
“I thought my son had crashed the party," he quipped.
Update: Here is the official transcript of the exchange from the White House.
Obama: Jack O’Malley -- where’s Jack -- Martin. Where’s Martin? Sorry. I was --
O'Malley: I thought my son was right here. (Laughter.)
Obama: Right, right, right.
