Senate Republican leader Mitch McConnell federal spending and the country's debt will dominate the congressional agenda for the next three months, and that debate about potential gun legislation in the wake of the Connecticut school shooting will take a back seat.

The Kentucky lawmaker tells ABC's "This Week" that lawmakers will wait to see what an Obama administration review led by Vice President Joe Biden might propose. McConnell says Congress will need to study any recommendations and then see what's appropriate to do.

But he says that over the coming months, nothing much beyond the country's finances will occupy the attention of Congress.
