Ann Romney to address convention Tuesday during network coverage

(CBS News) Ann Romney is going to have her moment on network television. Soon-to-be Republican presidential nominee Mitt Romney said Friday night that she'll speak at the GOP convention in Tampa on Tuesday and Florida Sen. Marco Rubio, who had offered her his prime-time spot preceding Romney's acceptance speech Thursday, will stay where he is.

Romney told radio host Hugh Hewitt that he had hoped the networks would not limit their coverage to one hour each on Tuesday, Wednesday and Thursday nights. "We are talking about the direction of the country. It's a little disappointing," he said. "But I should tell you that we've found a good way to make sure that Ann makes it on TV. We're going to have her speak on Tuesday night."

The candidate praised Rubio's generosity in offering to give his slot to Ann Romney, "but I want to have him speak, I want to hear him speak. So Ann's going to be on Tuesday, Marco Rubio's going to stay on Thursday just before me."

Ann Romney has put in a good deal of work on her speech and it's ready to go, Romney said. "Mine is still a work in progress - kind of early stage," he added. "I'm still working hard."
