Writing directly to the governor, he tweeted:

“Your guardsmen saved many lives and protected our country on this mission. Did you go visit them on the border to see for yourself? Or did you make your decision based solely on politics?”

Wisconsin law says commissioned officers can be punished for using “contemptuous words” against certain elected officials, including the President of the U.S., the Vice President and the Wisconsin Governor and Legislature, among other elected officials.

Kinzinger says after serving at the border, the drug smuggling and human trafficking that occurs there is a “security threat” to the nation.
