Could Sen. David Vitter Go To Jail?

Jail time is a possibility, for Senator David Vitter, if the D.C. Madam has her way:

The attorney for the "D.C. Madam" wants Sen. David Vitter, R-La., held in contempt of court for failing to adequately respond to a subpoena in her prostitution case. Lawyer Montgomery Sibley asked U.S. District Judge James Robertson to lock up the senator until he complies.

Vitter was subpoenaed to testify in mid-December at a hearing about telephone calls he placed to an escort service between 1999 and 2001, but the hearing was canceled. According to court papers, his attorney, Hank Asbill, said that the senator had no records requested by the defendant, Deborah Jeane Palfrey.

Nonetheless, her attorney told the court that Asbill "refuses to indicate what efforts were made by Sen. Vitter to comply with the subpoena of his documents" and that he wants the senator held in contempt. The judge has not ruled.

Should Vitter be held in contempt?
