The House Ethics Committee will investigate allegations that Rep. Corrine Brown, D-Fla., violated the code of official conduct in connection with campaign finance and other financial dealings, it said on Wednesday.
But the panel will defer its probe while the Justice Department is conducting its own investigation.
In its statement, the Ethics panel said it was looking into allegations that Brown used campaign funds for personal purposes, failed to comply with tax laws and made false statements and disclosures to the House and the Federal Election Commission.
The committee also suggested Brown may have improperly solicited donations and used official resources for non-official reasons.
Brown had no comment on the Ethics Committee investigation.
In a January statement, Brown linked a Justice Department subpoena to a high-profile fight she was having over congressional redistricting. She had said her district, which includes parts of Jacksonville and Orlando, was “under siege by other political forces.”
“It is not surprising that every time we go through the redistricting process some tangential investigation comes up,” Brown said at the time.
The Ethics Committee has in the past let federal law enforcement take the lead on investigations it, too, is pursuing.
