A spokesman for Republican House Speaker Paul Ryan says U.S. Rep. Pat Meehan informed Ryan of his decision on Thursday.

 Meehan is the fifth member of Congress to resign or abandon re-election amid a national reckoning over sexual misconduct in the workplace.

The former aide is three decades younger than Meehan. Her complaint came to light Jan. 20 in a New York Times report, citing unnamed people. The settlement was secret under confidentiality provisions, and Meehan refuses to say how much taxpayer money was involved.

Meehan denies he did anything wrong and says he followed the advice of House lawyers and Ethics Committee guidance.
