McCaskill: Republicans need to get specific on spending cuts

McCaskill said Democrats have done their part in spurring economic growth but "we're going to continue to focus like a laser on the middle class and small businesses. But we've got to do a better job of communicating."

Earlier Tuesday, Republican Rep. Marsha BlackburnMarsha BlackburnCorker pressed as reelection challenges mount GOP braces for Bannon primary attacks Air Force One is Trump’s new boardroom MORE (Tenn.) was asked on MSNBC what programs she would cut from the budget, and she targeted "discretionary" spending. She said discretionary spending doesn't include defense or homeland security. She didn't list any specific cuts from the budget. 

Discretionary spending makes up about one-third of the entire federal budget. Non-defense discretionary spending accounts for about 13 percent of the budget.
