Kenner Mayor Mike Yenni has told supporters he will make an official announcement on March 18 about “his decision on seeking the office of Jefferson Parish president” in the Oct. 24 elections.

In a “save the date” card mailed out Wednesday, Yenni said he will make his official announcement at 6:30 p.m. at Chateau Golf & Country Club in Kenner.

Many observers of the political scene in Jefferson have long expected Yenni to try to succeed Parish President John Young, who is leaving the job to run for lieutenant governor.

Yenni’s grandfather and uncle were Jefferson Parish presidents, and he has said that following in their footsteps has always been a goal of his. But he also has said his sole focus at the moment is on his job as Kenner’s mayor. He is about a year into his second four-year term.

A source close to Yenni said Wednesday that the mayor is considering several options for public office.

So far, the only declared candidate for the parish presidency is Elton Lagasse, a third-term parish councilman and former superintendent of Jefferson’s public schools.

Yenni, 38, was formerly director of Jefferson Parish’s Citizens Affairs Office, as well as the chief administrative officer for Ed Muniz, Kenner’s mayor from 2006 to 2010.

Yenni began the year with $67,482 in his campaign finance account, according to an annual filing submitted Jan. 19.
