Rep. Trent Franks, R-Ariz., is the third member of Congress to announce his resignation this week, saying that he had discussed surrogacy with two female subordinates.

Sen. Al Franken, D-Minn., facing multiple allegations of sexual misconduct, announced Thursday that he will be resigning. Speaking on the Senate floor, Franken said serving in the Senate has been "the great honor of my life" and that nothing he has done as a senator "has brought dishonor" on the institution. But he said, "it's become clear that I can't both pursue the Ethics Committee process and at the same time remain an effective senator" for the people of Minnesota.

Rep. John Conyers, D-Mich., said he will step down from Congress as of Tuesday, amid allegations of sexual misconduct leveled by multiple women.

The longest-serving member of the House of Representatives is the latest lawmaker caught in the wave of sexual harassment claims.
