President-elect Donald Trump met with retired Marine Gen.James Mattis and called him "impressive." These comments are fueling speculation that he could be tapped as secretary of defense. Trump met with Mattis on Saturday, as he held a series of meetings at his Bedminster golf resort. Mattis is an outspoken ex-military leader who butted heads with the Obama administration over Middle East policy, particularly over Iran, which he has called “the single most enduring threat to stability and peace in the Middle East." Now we just wait and see if Trump taps Mattis for his Cabinet.
