Singer and actress Cher was not happy to hear that U.S. Rep. Trey Radel, R-Fla., returned to work on Capitol Hill Tuesday after he pleaded guilty to a misdemeanor charge of cocaine possession in November. She clearly doesn’t believe in politics after drugs and took to Twitter to vent her feelings after Radel returned to work following his completed stint in rehab.

"I cannot express how sorry I am. I ask for your forgiveness. I've let down our entire country. I have let down my colleagues on both side of the aisle. I've let down my family," Radel said, according to CNN, when he returned to Capitol Hill after his leave of absence.

The congressman wants to earn back his reputation, which many believe has been tarnished. "In front of a U.S. representative's name, they often put the word 'honorable,' and I will work hard every day to restore that honor -- rebuilding trust and making amends, with our country, my constituents, my colleagues, my wife and my 2-year-old."

Though Radel, 37, would like to be seen in a positive light with the public, he said he's not concerned about re-election and that it was the furthest thing from his mind after spending 28 days in treatment. CNN, however, pointed out that he will need to start thinking about his political future soon, since State Rep. Paige Kreegel is challenging Radel in August’s GOP primary. The Southwest Florida district is heavily Republican.

Though naysayers like Cher might think Radel has no place anymore on Capitol Hill, mental health and addiction expert Jamison Monroe Jr., CEO of Newport Academy, told the International Business Times in November that although addiction might be seen as a weakness, it’s really an disease that can be overcome. “There is life after addiction,” Monroe said. “Recovery is possible.”

Radel has admitted to having a disease and promises to work towards beating it. He went from respected politician to disgraced after he was found using cocaine during an undercover sting operation in Washington, D.C. Though he has admitted his cocaine use, Radel said he mainly struggled with alcohol. He has been sentenced to one year of probation for his crime.
