(CNN) A combat veteran running for US Congress in Arizona suspended his campaign on Monday after a relapse and drug overdose.

"Today, I have suspended my campaign for the US House of Representatives and am seeking treatment for substance abuse disorder. I will fully cooperate with local authorities on any matters arising from my recent relapse and overdose," Chris Taylor, a Safford, Arizona, city council member, told CNN in a statement. The Arizona Republic reported Monday that Taylor was suspending his campaign after a heroin overdose last week.

"I'm not going to hide from this. I'm not ashamed of what happened. I wish to sincerely apologize to the amazing people who have supported me," Taylor said.

He added, "I don't know what went wrong. I recently relapsed after having so many solid years in sobriety. I have to figure out where I went wrong."

Taylor, a father of two, said, "The only thing I can do is face this head on in complete humility and put one foot in front of the other so that I can get the help needed to be the father and husband that my family deserves. I'm human and I have never pretended to be anything but."
