Donald Trump's sister has retired as a federal appellate judge in Philadelphia, ending a civil misconduct inquiry launched after a report that she participated in Trump family schemes to dodge taxes.

The retirement of Maryanne Trump Barry was revealed in an April 1 order signed by a top court official in New York, where the misconduct case was assigned to prevent conflicts of interest for judges who knew Barry.

Barry's voluntary Feb. 11 retirement ends the review stemming from claims based on the news article alleging that Barry may have committed misconduct relating to tax and financial transactions that occurred mostly in the 1980s and 1990s.

The order said the complaint process was meant to correct conditions interfering with the "effective and expeditious" administration of court business. It said the resignation meant that Barry can no longer perform any judicial duties and thus can no longer be investigated.

After her brother's election, Barry gave up her court staff and took inactive status in early 2017.

A Republican, she was nominated for a judgeship by President Ronald Reagan and was elevated to the circuit court by President Bill Clinton.
