Money is seen in the back pocket of U.S. President Donald Trump as he boards Air Force One at Moffett Federal Airfield in Mountain View, California. Earlier in the day, the President attended a private fundraiser in Silicon Valley. Following his departure from California, Trump clarified to members of the news media on Air Force One that he always carries around cash. "I don’t carry a wallet because I haven’t had to use a credit card in a long time. I like to carry a little something. I like to give tips to the hotel.”
