President Bush said Wednesday that he is considering a fresh plan to cut tax rates for U.S. corporations to make them more competitive around the world, an initiative that could further inflame a battle with the Democratic Congress over spending and taxes and help define the remainder of his tenure.

Advisers presented Bush with a series of ideas to restructure corporate taxes, possibly eliminating narrowly targeted breaks to pay for a broader, across-the-board rate cut. In an interview with a small group of journalists afterward, Bush said he was "inclined" to send a corporate tax package to Congress, although he expressed uncertainty about its political viability.

Democrats quickly returned fire, noting that Bush inherited a surplus that turned into a deficit and that he never vetoed a spending bill during the six years that Republicans controlled Capitol Hill, even as the budget grew 50 percent.
