Sens. Tom Carper and Chris Coons joined Senate Democrats in writing a letter to President Donald Trump, Leader Mitch McConnell and Chairman Orrin Hatch, urging Republicans to come to the table and work with Democrats in a bipartisan way on the Senate’s next critical item — tax reform.

Carper, Coons and 43 of their Democratic colleagues laid out their three main tenants ahead of any negotiations and said they hope to work with the GOP to craft legislation that prioritizes working families over the wealthiest few and special interests.

First, the senators wrote, they believe “that tax reform should not increase the tax burden on the middle class.” Second, they wrote that it is “crucial that tax reform legislation go through regular order and not reconciliation;” and, third, that tax reform should be focused on providing a revenue base that meets the needs of our country.”
