Treasury Secretary Timothy Geithner on Tuesday said the unemployment rate could rise for a couple of months before it goes down.

It's possible you're going to have a couple of months where it goes up, he said on ABC's Good Morning America show. But what we expect to see ... is an economy that's gradually healing, of course we want to do what we can to reinforce that process.

He also said he would stay in his job as long as President Barack Obama wanted him there.
