COLORADO SPRINGS - The FBI is now taking on Anthony Jackson's discrimination case against Fort Carson.

In April, the civilian employee said he was being intimidated on the job and claims the final straw came when he was threatened with a noose.  "Basically, what the individual told me is, 'you don't want me to hang your ass,'" Anthony Jackson says. 

Jackson goes by AJ and works as a range inspector on Fort Carson.  He says a coworker brought a rope into the office.  "Playing with the rope, tying it into a noose," Jackson says of his colleagues' behavior. 

 Jackson reported it to his boss, but says it was just the latest in what was months of intimidation and discrimination on the job.  "They are supposed to be your coworkers," says Jackson, "you're supposed to be able to trust your superiors." 

Jackson hasn't been to work since the noose incident ten months ago.  He says he's been diagnosed with post-traumatic stress disorder because of the situation at work.  "I've been trying to tolerate it," Jackson says, "but it's caused me emotional pain and suffering." 

He says he's documented numerous incidents over the past year when he is singled out to do jobs other employees aren't asked to do.  Jackson says coworkers are trying to get him to quit.  "Sometimes it gets hard to talk about," says Jackson. 

Jackson says he's not going to leave until the issues are addressed.  He says the problem is much bigger than just his situation.  "If people just know what is going on out at Fort Carson, the difference between what blacks have to go through out there, it's serious," he says, "it is a serious problem." 

Fort Carson officials said they can't comment on an ongoing investigation.
