U.S. income taxes are due on April 15. Because the 15th falls on a Sunday this year, and because Monday, April 16, is a holiday in Washington, D.C., taxes can be filed as late as Tuesday, April 17.
The news conference will feature Congressman Dave Camp (R-MI), Chairman of the House Ways and Means Committee, and Congressman Mike Pompeo (R-KS).
Grover Norquist and speakers from The Heritage Foundation, FreedomWorks, and the National Taxpayers Union will also attend.
