Washington (CNN) Rep. Blake Farenthold announced he's resigning from the House of Representatives effective Friday, a few months after news broke he used taxpayer money to pay a settlement to a former aide who accused the Texas Republican of sexual harassment and other improper conduct.

After his announcement, the National Republican Congressional Committee, which works to elect GOP candidates to the House, requested he pay back the money that was used for the settlement.

"I hope Blake is true to his word and pays back the $84,000 of taxpayer money he used as a settlement. As I have said repeatedly, Congress must hold ourselves to a higher standard and regain the trust of the American people," NRCC Chairman Steve Stivers said in a statement. "I'm confident we'll have a Republican in this seat come November."

Friday night, a spokeswoman for House Speaker Paul Ryan said Farenthold had committed to paying back the settlement.

"Mr. Farenthold made a commitment that he would reimburse taxpayers for the settlement," AshLee Strong said. "He reiterated his commitment to the speaker and the speaker expects him to follow through."
