The Senate Ethics Committee dismissed a misconduct complaint against Sen. Ruben Gallego (D-Ariz.) on Monday, saying it found no evidence that the Arizona Democrat violated federal law, Senate rules or standards of conduct.

The six-member bipartisan committee sent Gallego a letter dated June 26, obtained by NBC News, informing him that it had closed the investigation. The letter said the panel appreciated Gallego’s “full cooperation” and noted that it “retains the authority to revisit this matter should additional facts become known.”

The complaint, filed by Rep. Anna Paulina Luna (R-Fla.), alleged “campaign finance violations and inappropriate conduct of a sexual nature,” according to the committee’s letter.

Luna filed the complaint after reports that then-Rep. Eric Swalwell (D-Calif.) had harassed and sexually assaulted multiple women. Swalwell resigned from Congress in April. Gallego has said he was friends with Swalwell but denied any personal misconduct and said he did not know about Swalwell’s alleged actions.

On April 23, Luna wrote on social media that she had “heard of four women who have had multiple and uncomfortable/inappropriate advances/comments/touching, etc. from Senator Gallego.”

In a statement Monday, Gallego said the dismissal reaffirmed what he had said about the accusations “from the beginning: they were right-wing conspiracies peddled by far-right activists like Anna Paulina Luna, the White House and their allies.” He said he looked forward to an apology from Luna “for weaponizing the ethics process while refusing to investigate historic corruption that’s making life harder for families.”

Politico reported earlier in June that Gallego used campaign donations to pay for trips with his wife and childcare expenses, which Gallego did not dispute. He told Politico that “with the rising costs of childcare and the burden it has on the budgets of American families, Democrats and Republicans in Congress and the White House alike regularly travel with their wives and children, as is permitted by the FEC.”
