U.S. President Donald Trump has indicated that he isn't sure how long his Defense Secretary James Mattis plans to stay in his administration.
In an interview with CBS's "60 Minutes" that was broadcast on Sunday,... President Trump said the two have "a very good relationship", but suggested there was the possibility he could step down at some point.
Trump added that Mattis is "sort of a Democrat",... increasing speculation the two have been at odds over certain issues.
