Updated with Trump's latest comments:
U.S. Sen. Claire McCaskill is continuing to hammer away at some GOP hints that Republicans might try to trim or privatize Medicare and Social Security. But on Tuesday, she also took on an issue closer to home – defending Boeing Co. from President-elect Donald Trump.
Trump, a Republican, caused Boeing’s stock to briefly go into freefall Tuesday after he tweeted that he wanted to cancel the aircraft giant’s contract to build new Air Force One aircraft. Trump claimed the price was too high.
