(CNSNews.com) – U.S. government employees and their families have thus far contributed $396,550 to President Barack Obama's reelection campaign, making them one of the top five sources of cash for the campaign to reelect the president, according to Opensecrets.org.

Employees of the U.S. State Department and their families have, by themselves, contributed $213,256 to the Obama reelection campaign.
