Thomas Athans, 46, co-founder of the liberal TalkUSA Radio network, was stopped by police who were investigating prostitution at the hotel, according to a police report.

Mr Athans, in a statement issued by his attorney, apologised and said he 'fully cooperated with law enforcement. My family and I are dealing with this matter in a personal and private way.'

Ms Stabenow, a Democrat from Michigan, said that she wanted 'folks to know that I'm grateful for their prayers and support and this is a family matter that is very difficult but we are going to work through it.' 'I think it's important to continue to do my job and to focus on people in Michigan who are hurting every day and expect that I'm going to fight for them everyday,' she said.

The Detroit Free Press and The Detroit News first reported on the case in stories on their Web sites on Wednesday.

Troy police had set up a stakeout at the Residence Inn after learning of suspected prostitution at a room there, the police report said. Officers said they saw Mr Athans enter the room on Feb 26 and leave 15 minutes later.

They stopped Mr Athans' car and informed him they were investigating prostitution. He told the officers he had used the Internet to make a date with a prostitute and paid her US$150 for oral sex at the motel, the report said.

Police did not bring any sex charges against Mr Athans but later mailed him a ticket for driving with a suspended licence.

Mr Athans' licence was suspended last year for failure to pay a ticket for driving without proof of insurance, according to the Michigan Department of State. Court records show he paid a U$115 fine, and the state restored his license March 11.

He was cooperative and 'didn't drop any names or ask for preferential treatment,' said department spokesman Lt Gerry Scherlinck.

Arrested
Police said they arrested Alycia Martin, 20, of Westland in the hotel room on a charge of prostitution. She was arraigned March 12 and freed on US$100 bail pending a hearing on April 22.

Ms Stabenow and Mr Athans married in February 2003. Mr Athans, an Air Force veteran, worked as an aide in Ms Stabenow's Detroit office prior to their engagement and marriage and also worked for Rep Dale Kildee, also a Michigan Democrat.

Mr Athans started TalkUSA Radio in 2006 after leading programming at Air America, the liberal radio network that declared bankruptcy that year.
