As many as four Colorado lawmakers have come together to try and regulate medical marijuana dispensaries. On Monday, they sent in a request to the Attorney General Eric H. Holder Jr. to halt the ongoing raids on medical marijuana operations.

As has been stressed by the lawmakers, the raids are discouraging dispensary operators and medical marijuana patients and growers from working with them on regulations which have been proposed.

The letter was sent in jointly by Senators Chris Romer and Nancy Spence and Representatives Tom Massey and Beth McCann.

"It's kind of hard to build trust in the environment that's been created by these raids", Sen. Romer said.

While declining to share any additional comments, a Justice Department spokesperson, Tracy Schmaler, said that the agency would review the letter.
