(CNN) - U.S. Rep. John Sullivan, of Oklahoma, checked himself into the Betty Ford Center in California on Thursday night for treatment for alcohol addiction, according to a written statement from his office.
Sullivan, a Republican from Tulsa, said in the statement that he will be taking a leave of absence from Congress while he seeks treatment.
"I value my relationship with the citizens of Oklahoma's First Congressional District, whom I am privileged and honored to have served for the past eight years," Sullivan said in the statement, released Friday evening. "So, I wanted to be open and honest on this tough situation."
Sullivan is married with four children, according to the biography on his Web site.
"My family is going through a difficult time right now, and I ask that you respect their privacy and keep us in your thoughts and prayers," he said. "With God's help and strength, I will get through this most challenging time in my life."
The Betty Ford Center, named for the former first lady, opened in 1982. It specializes in treatment of dependency on alcohol and other drugs.
