From AP’s Jennifer Loven, word that there’s a tentative Capitol Hill deal on the $700 billion Wall Street bailout. The terms are entirely sketchy, but it sounds like no agreement has been reached on helping distressed mortgage holders, only their bankers’ bankers:

The tentative accord would give the Bush administration just a fraction of the $700 billion it had requested up front, with half the money subject to a congressional veto, congressional aides said. Under the plan, the Treasury secretary would get $250 billion immediately and could have an additional $100 billion if he certified it was needed. The last $350 billion could be blocked by a vote of Congress under the arrangement, designed to give lawmakers a stronger hand in controlling the unprecedented rescue…

There were signs that the conservative-leaning House Republican Caucus was not on board. Both of Congress’ Republican leaders, Rep. John Boehner and Sen. Mitch McConnell, issued statements saying there was not yet an agreement. But Banking Chairman Chris Dodd, D-Conn., and Republican Sen. Bob Bennett, among others, said negotiators from Congress and the administration had arrived at a deal that could win approval.
