The climate change bill to be brought to the floor of the House will have enough votes, House Majority Leader Steny Hoyer (D-Md.) said Friday.

But the debate and eventual vote on the bill may roll over into Saturday, Hoyer cautioned during an interview on Bloomberg News.

"I think we're going to have 218 votes -- a majority of the votes -- when this bill is voted upon later this afternoon," Hoyer said.

"It may roll into tomorrow -- I don't know that that could be the case, but we're going to take it under consideration. We'll see how long it takes to consider it," the second-ranking House Democrat added.

Hoyer also defended the bill against claims from environmental groups like Greenpeace that House Democrats ceded too much of the bill's substance in order to win enough votes to pass the landmark deal.

"When you say have we given away too much, I don't think that that's the case," Hoyer said. "In fact, I think we've brought a bill that's a balanced bill."
