The 37 year-old Florida Republican is serving his first term in Congress after winning office last November.
A spokesman for the U.S. Attorney's office said Tuesday that the charges come with a maximum 180 day imprisonment and/or $1,000 fine.
“I'm profoundly sorry to let down my family, particularly my wife and son, and the people of Southwest Florida," Radel said in a statement released by his office. "I struggle with the disease of alcoholism, and this led to an extremely irresponsible choice. As the father of a young son and a husband to a loving wife, I need to get help so I can be a better man for both of them.”
“However, this unfortunate event does have a positive side. It offers me an opportunity to seek treatment and counseling. I know I have a problem and will do whatever is necessary to overcome it, hopefully setting an example for others struggling with this disease.”
Radel is a former journalist and TV news anchor.
"Members of Congress should be held to the highest standards, and the alleged crime will be handled by the courts," a spokesman for House Speaker John Boehner said in a statement. "Beyond that, this is between Rep. Radel, his family, and his constituents."
