Stocks climbed to record highs Thursday following the Senate's acquittal of President Trump as well as China announcing plans to lower tariffs on U.S.-made goods and a strong read on U.S. productivity.

"If we didn't win, the stock market would've crashed," he said. "The market was going up a lot before the election ... and then it went up tremendously from the time we won to the time we took office."

Trump was acquitted on both articles of impeachment late Wednesday, in a vote that was mostly along party lines.
