Democrats and Republicans have been sparring over the tax law signed by President Trump at the end of 2017 heading into November's midterms.

Democrats argue that the law primarily helps wealthy individuals and corporations and will lead to cuts to the social safety net, while Republicans say the law is helping the economy and the middle class.

There are signs that Democrats' message on the tax law is resonating with voters. A poll last month commissioned by the Republican National Committee found that most voters think the measure helps the wealthy and corporations more than the middle class.

The bus tour, organized by Network lobby for Catholic Social Justice, is scheduled to make stops in a number of states and districts across the country with competitive House and Senate races — including the districts of GOP Reps.
