June 10 (Reuters) - United Auto Workers President Shawn

Fain is under investigation by an independent federal monitor

over allegations of retaliation against other union leaders,

according to a court filing on Monday.

Monitor Neil Barofsky said he had opened an investigation in

February to review allegations, including that the UAW secretary

treasurer said she had faced retaliation for her refusal or

reluctance to authorize certain expenditures for Fain's office,

according to the filing. Barofsky also opened a probe into the

secretary treasurer's actions. The UAW declined to comment.
