President Donald Trump signed the historic GOP tax reform bill into law Friday morning. As he did so, the president told reporters in the Oval Office he was going to wait until after the new year to sign it, but he changed his mind, primarily because he wanted to prove to the American people he was keeping his promise to get the bill signed before Dec. 25. “I didn’t want you folks to say I wasn’t keeping my promise to sign the bill by Christmas,” he said.
