 (CNN) President Donald Trump on Wednesday unveiled a Republican framework for tax reform that calls for sweeping tax cuts and a simplification of the tax code, framing the effort in a speech as a historic opportunity. Trump said that while wealthy, "well-connected" people could "call me all they want, it's not going to help," saying he was "doing the right thing." And it’s not good for me, believe me.” 
 
 What would help both the country and his own legacy, Trump said, is when the economy "takes off like a rocket ship" after business taxes are dramatically cut. But Congress still has to fill in many important details before bringing to a vote legislation Trump hopes to sign before the end of the year. "This is a once-in-a-generation opportunity, and I guess it's probably something I could say that I'm very good at," Trump said during remarks in Indiana. I’ve been waiting for this for a long time." And he refrained from lashing out at specific Republicans for the failure of the GOP health care bill, saying “There were a couple of people that — I won’t say anything.”

 The proposed tax changeshe promoted include slashing the individual tax rates and reducing the corporate tax rate to "below the average of other industrialized nations." That, he said, would be "a revolutionary change, and the biggest winners will be the every day American workers as jobs start pouring into our country, as companies start competing for American labor, and as wages continue to grow." The President's tax reform framework proposes cutting the top income tax bracket from 39.5% to 35%, though the plan gives congressional committees latitude to create a fourth, higher income tax bracket. It would increase the child tax credit from $1,000 to an unspecified amount, and create a new $500 tax credit for non-child dependents, such as the elderly. Republicans also want to eliminate two taxes paid entirely by the rich and take away a deduction for state and local taxes that is used most heavily in some of the most wealthy, and Democrat-dominated, states. Senate Minority Leader Chuck Schumer, D-N.Y., said the framework released Wednesday “at best throws crumbs for some middle class people.” 
 
 “Has the president read his plan?” Schumer asked. Trump added that "tax reform has not historically been a bipartisan issue," drawing on the example of the Reagan tax cuts which were passed with significant Democratic support as he said he hoped Democrats would join in supporting the reform effort. "If Sen. Donnelly doesn't approve it -- because you know he's on the other side -- we will come here, we will campaign against him like you wouldn't believe," Trump said, pointing at Donnelly in the audience before suddenly offering a wide grin. "I think they're going to approve it, I think we'll have, actually I think we'll have numerous Democrats come across, because it's the right thing to do." Trump is the first president in four decades not to do so. "As it stands, the framework released today is missing many details that will be critical to determining whether working- and middle-class families truly stand to benefit," he said in a statement following the speech. “If Senator Donnelly doesn’t approve it — because, you know, he’s on the other side — we will come here, we will campaign against him like you wouldn’t believe,” Mr. Trump said as Mr. Donnelly looked on from the audience. "Our framework will stop punishing companies for keeping their headquarters in the United States. Indiana is the 25th state President Trump has visited since taking office 
 
 3 Indiana businessmen to help Trump make his case for tax reform package 
 
 Trump chose Indiana for Wednesday’s speech in part to talk about the state’s record of cutting taxes under then-governor Mike Pence, who is now his vice president. He called for reducing the personal income tax brackets from seven to three (12%, 25% and 35%), doubling the standard deduction for married and single filers (to $24,000 and $12,000 respectively), slashing the corporate tax rate to 20% and eliminating the estate tax -- among other proposals. Indiana Democratic Party Chairman John Zody said Wednesday the “historic” tax relief Pence promised Hoosiers “only added up to a paltry $50 per household last year — barely enough for one tank of gas.” 
 
 Trump highlighted how the proposal would benefit individual Hoosiers, including Kip Tom, a seventh-generation farmer who was on Trump’s agriculture advisory committee. And a lot of very wealthy people feel the same way, believe me." In Indianapolis, he offered specific numbers to back up his calls for the biggest changes to the tax code in decades. The framework also gives Congress the option of creating a higher, fourth, rate above 35 percent in the tax plan to ensure that the wealthy are paying their fair share.
– President Trump launched his push for tax reform Wednesday in Indianapolis, promising a "once-in-a-generation opportunity" and "revolutionary change." "Under our framework, we will dramatically cut the business tax rate so that American companies and American workers can beat our foreign competitors and start winning again," USA Today quotes Trump as saying. The New York Times reports the proposed framework reduces the corporate tax rate to 20%, doubles deductions for married and single filers to $24,000 and $12,000 respectively, and reduces the number of tax brackets from seven to three. The top bracket would see a reduced tax rate; the lowest bracket would see an increased tax rate. Overall, Trump claims the plan represents the biggest tax cut in history: "There's never been tax cuts like we're talking about." Trump is promising the middle class will be "the biggest winners" of his tax plan, which will cause "jobs to start pouring into our country." But the framework presented lacks details to show whether that would or would not be the case. (CNN reports Trump also claims the plan is "not good for me," but that's impossible to prove without his tax returns.) The framework does, however, include details that will specifically benefit rich Americans, for example by getting rid of inheritance taxes paid by the country's wealthiest families. Without further specifics, the head of the nonpartisan Committee for a Responsible Federal Budget calls Trump's tax plan "nothing more than a fiscal fantasy." Trump says he wants to work with Democrats to fill in those details, but Republican leaders say they'll likely use a special rule to pass tax reform without Democratic support.
