President Donald Trump faces many hurdles in delivering his promised tax cut, but none may be more formidable than the congressional calendar.

The president will call for cutting taxes for individuals and lowering the corporate rate to 15 percent after briefing GOP leaders.

IRS Commissioner John Koskinen testified at a Senate hearing Thursday about tax season, a day after a group of House Republicans wrote to President Trump asking him to fire Koskinen.

Senate Majority Whip John Cornyn said Thursday it’s uncertain whether Congress will offset the tax cuts that Republicans hope to deliver with new revenue, creating the chance that their tax-overhaul plan would be limited to 10 years.

GOP lawmakers are hearing arguments from retailers and other companies that the import changes would hurt consumers. But a new report suggests solid information may be hard to come by.

A news report that the European Union and other U.S. trading partners are preparing to challenge House leaders’ proposal to overhaul U.S. corporate taxes spurred the plan’s leading congressional advocate to declare that it would survive “any challenge that they bring.”
