Was firing Van Jones unconstitutional?

Wake up Obama: Beckism is Winning!
by Patriot Daily News Clearinghouse
Excerpt:
For example, when Meteor Blades posted the announcement that Van Jones had resigned, some Kossacks responded along the lines of how can we defend Van Jones when his truther beliefs violated the rules of Daily Kos? The answer is that we defend Van Jones because he is a Democrat who did not violate any laws. (Bold emphasis are mine)

Surely Mr. Jones can find something in the Bill of Rights or the 5th, 9th or 14th Amendment or something to fight his being dismissed from his government job. Were I in his position, I would hate to have that on my résumés.

-Mr. President! Van Jones gotta go! Fire him!
-What law has he broken?
-Huh??
-Show me anywhere in the U.S. Constitution the law he has broken while working here in the White House and I will take your advice under advisement. From my knowledge of the Constitution, he has broken no law so put up or shut (tuh fuck) up! Last time I looked, this is a nation of laws. We can’t just go around firing people because you don’t like them. What‘s wrong with you, my good man?
As always,
