The White House is changing its tactics for dealing with Congress when it comes to overhauling the tax code after the failed attempt to repeal Obamacare.

President Donald Trump's administration will release the broad outlines of a tax plan Wednesday, and then spend the next four to six weeks building congressional support before turning the ideas into legislative text sometime in the summer, Marc Short, White House head of legislative affairs said to reporters Tuesday. While it may take until the end of the year for the bill to become a law, it isn't likely to stretch into 2018, Short said.

The timeline contrasts with the White House's approach to repealing the Affordable Care Act. Trump stayed on the sidelines for most of the debate while House GOP leaders crafted a bill and tried pitching it to fellow members. Only in the final stretch did Trump try to engage House lawmakers, calling on them to pass the bill and threatening to move to other issues if they didn't. GOP leaders canceled a planned vote last month after concluding they didn't have enough support. Prospects for repealing the law, known as Obamacare, remain in doubt.
