The Globe and Mail reports in its Thursday edition that former U.S. Treasury secretary Larry Summers will resign from teaching at Harvard University as the campus reviews his ties to the late convicted sex offender Jeffrey Epstein, the university announced Wednesday. An Associated Press dispatch to The Globe reports that Prof. Summers, who has been on leave since November and whose name appeared hundreds of times in newly released Epstein files, will step down at the end of the school year, according to a statement from Harvard spokesman Jason Newton. "Professor Summers has announced that he will retire from his academic and faculty appointments at Harvard at the end of this academic year and will remain on leave until that time," Mr. Newton said. In a statement, Prof. Summers said it was a difficult decision and expressed gratitude to the students and colleagues he worked with over 50 years, including five as Harvard's president. He said, "Free of formal responsibility, as President Emeritus and a retired professor, I look forward in time to engaging in research, analysis and commentary on a range of global economic issues." Prof. Summers served as treasury secretary under former president Bill Clinton.
