June 29 (UPI) -- A Senate ethics panel has dismissed misconduct allegations against Sen. Ruben Gallego after an investigation, the Arizona Democrat's office said Monday.

The six-person, bipartisan Senate Ethics Committee sent Gallego a letter dated June 26 (obtained by NBC News) in which members said they found no evidence that his actions "violated federal law, Senate rules or related standards of conduct."

The letter said the complaint, filed by Rep. Anna Paulina Luna, R-Fla., alleged "campaign finance violations and inappropriate conduct of a sexual nature."

"The dismissal by the Ethics Committee reaffirms what I have said about these accusations from the beginning: they were right-wing conspiracies peddled by far-right activists like Anna Paulina Luna, the White House and their allies," Gallego said in a statement Monday, Axios reported.
