He has sought a "backstop" that would create automatic tax increases if the tax bill doesn't spur strong economic growth as Republicans have promised. While Republicans claim that future lawmakers will extend the tax cuts, that's no guarantee for the people who will be hurt if they don't. Democrats backed out of a planned meeting after Trump attacked them on Twitter.
Trump, meanwhile, is fulminating about the need for a win after promising his own supporters that his presidency would be one long victory lap.
After Trump's meeting with Senate Republicans, Corker said, "I think we're getting to a very good place on the deficit issue".
The current Senate bill completely repeals the state and local tax deduction, which helps reduce the tax bills of more than 43 million families.
The final tax bill will not be entirely about taxes.
The House's chief tax-writer says ending the "Obamacare" requirement that everyone have health insurance - an element of the Senate bill - is a move the House also is likely to accept. "With just a few changes, some mathematical, the middle class and job producers can get even more in actual dollars and savings". Afterward, Collins said Trump and other GOP leaders agreed to the property tax provision. It would eventually have to be reconciled with the tax measure recently passed by the House.
"We're looking forward to finding common ground in conference, finalizing the details, and sending this historic legislation to the President by the end of the year", Brady said in remarks to the American Enterprise Institute.
The demands from Johnson, Corker and other GOP Senators put party leaders in a hard position.
Trump said as he meets with Republican House Speaker Paul Ryan and Republican Senate Majority Leader Mitch McConnell that Schumer and Pelosi are weak on crime and combating illegal immigration and want to increase taxes. There are signs however that other senators are trying to get to yes, including Alaska's Lisa Murkowski and Maine's Susan Collins.
An aide to Johnson said that despite frantic efforts to appease the Wisconsin senator, he couldn't yet commit to vote yes. "So far, we haven't gotten there".
Spokespeople for the Senate Finance Committee, which drafted the bill, did not immediately respond to a request for comment.
Corker refused to say whether he would back the bill on Tuesday, as he works to create a mechanism to offset its costs. Those are Trump's nicknames for Democratic Sen. Jeff Flake, is balking at "gimmicks" which he said include phasing out individual tax cuts over the life of the proposed law but which keep corporate tax cuts permanent. Bill Cassidy, R-La. "If I do that, consider me drunk".
