Embattled Rep. Trey Radel (R-Fla.) has no plans to resign his seat in Congress, he said Thursday, declaring a desire to return to Congress after being sidelined by a drug arrest.

"I love what I do and I'm going to return to what I do, what you sent me to do in Washington D.C., which is working for you and your family while I relish mine," Radel said at a news conference, according to the Associated Press.

Radel made his remarks  at his Cape Coral campaign office after spending four weeks in rehab. He said he think members of Congress should undergo drug testing.

"I think members of Congress can and should be tested," Radel said, adding, "maybe it will help someone else in the future."

Radel pleaded guilty to cocaine possession last month. He was sentenced to one year of probation.

The freshman congressman has resisted multiple calls for his resignation, including from the Florida state Republican Party.
