President Barack Obama is challenging Republican lawmakers to present a plan for a smaller-scale deficit reduction program as he attempts to steer them toward his $4 trillion goal, a Democratic aide said.

Obama plans to hold a press conference at 11 a.m. in Washington today, his fifth public remarks on the debt in a week, as he presses lawmakers to reach an agreement to raise the $14.3 trillion U.S. borrowing ceiling before an Aug. 2 deadline. The president and bipartisan congressional negotiators agreed to meet every day until they reach a deal, said one legislative aide on condition of anonymity.

They are divided over taxes and entitlements. Republicans reject Democrats' call for more tax revenue and instead are pressing to cut entitlement programs such as Medicare and Social Security. Democrats insist even the Republicans' proposal for a smaller deficit-cutting plan must include more taxes from higher-income Americans. Obama has said he is willing to cut entitlements in exchange for a Republican agreement to increase taxes.
