The $220,000 paid to former staffer Winsome Packer in 2014 is by far the largest known settlement involving Congress and accusations of sexual harassment in recent years.

But few, if any, of the lawmakers who served on the congressional commission where Packer worked seem to have been informed about it until the sum was reported by Roll Call on Friday.

The settlement, paid by taxpayers through the Treasury Department, capped four years of negotiations, internal complaints, investigations and court proceedings in Packer’s case.

She alleged in court and in congressional complaints that her boss, Florida Democratic Rep. Alcee L. Hastings, subjected her to two years of unwanted sexual advances while she was working in Vienna for the Commission on Security and Cooperation in Europe, also known as the Helsinki Commission — and threatened her job when she resisted.
