A new Penn-Wharton report shows that the House GOP bill would increase federal deficits substantially in both the short-run and the long-run in ways that would vastly increase the difficulty of passing it in the Senate, CNBC reports.

“The Penn-Wharton model shows that the House GOP tax bill would reduce tax revenue by $1.7 trillion over the next 10 years. That exceeds the $1.5 trillion permitted under the budget ‘reconciliation’ rules that allow Senate Republicans to sidestep Democratic filibusters.”

“Moreover, the Penn-Wharton model projects that the House GOP bill would lost another $2.6 trillion in revenue during the 12 years after 2027. Under the no-filibuster rules, the tax bill would not be permitted to increase the deficit at all after its first 10 years.”

“A group of Democratic senators is set to huddle with a top White House official to discuss potential changes to the Republican tax plan Tuesday,” the Washington Post reports.

The Democrats include Sens. Joe Manchin III (WV), Heidi Heitkamp (ND) and Sherrod Brown (D-OH).

“What, if any, substantive change to the emerging proposals might come out of the meeting is unclear — but it will allow the White House and the moderate Democrats to claim they’re at least trying to forge bipartisan consensus.”

“House Republicans’ tax bill would increase taxes for 12 percent of Americans next year, according to a new report from the nonpartisan Tax Policy Center. By 2027, at least 28 percent of Americans would see their taxes rise, the report says. Many of those taking a hit would be people who make less than $48,000 a year,” the Washington Post reports.

“The vast majority of Americans would get a tax cut if the bill becomes law… but the rich would benefit the most. The finding comes amid intense debate over whether this bill does enough to help the middle and working classes, a key promise of President Trump.”
