This is an easy question. A congress person says something bad about the president. A general says that it is not true. Which one do you believe?
The congress person is a member of congress. That's about it.
The general retired from the United States Marine Corps with several stars on his shoulder. He did three years in the Middle East war. He enlisted as a private, went to college, and was commissioned. He is currently chief of staff to the president.
Which one do you pick?
