New York Board of Regents Chancellor Merryl Tisch plans to serve as chairwoman of William Thompson's mayoral campaign.

Their association goes back to the 1990s when she served on the Board of Regents and he was president of the city Board of Education.

The Wall Street Journal  reports that her support of the former city comptroller could boost his chances among voters concerned about city schools. Her family ties could also help Thompson raise money. Her husband is the chief executive of Loews Corp.

She will not be involved in day-to-day campaign responsibilities. Rather, she will serve as a high-profile ambassador and fundraiser.

Tisch said that campaign lawyers she consulted saw no conflict between her state-level role and involvement in Thompson's campaign.
