UPDATE: 12.17.2007, 8:45 p.m., Bloomberg News’ updated post has additional information.

There are reports that the Securities and Exchange Commission has asked a federal judge to compel Birmingham mayor Larry Langford to testify as part of a continuing investigation after the mayor testified before the commission last week and did not answer questions, citing “privileges and a ‘right under the United States Constitution” as his reasons.

The official litigation release offers additional information and details.

According to this report filed earlier this afternoon, no comment has been released as of yet from the mayor’s office.
