Vice President Joe Biden is said to be “ticked off” with the way President Barack Obama treated Defense Secretary Chuck Hagel, who announced his resignation early this week.

While Hagel put forth that it was his decision, rumors suggest he was asked to step down and Biden is not real happy about it, according to the Washington Times.

Biden and Hagel are pals from their days together in the U.S. Senate.

“A lot of this is about 2016,” columnist Byron York said Friday on Fox News. “Joe Biden is keeping that option open for 2016, and there is nothing harder than trying to run for the third term of a president whose approval rating is around 40 percent.”

York pointed out that Biden walks a fine line between trying to distance himself from Obama on some issues, while trying to appear loyal to his administration.
