NEWARK, N.J. (AP) — New Jersey Gov. Chris Christie’s wife has left her lucrative job at a Wall Street firm as her husband prepares for a potential run for the White House.

A spokesman for Christie’s office confirmed Friday that Mary Pat Christie recently resigned as managing director at Angelo, Gordon and Co. and is putting her career on hiatus.

Spokesman Kevin Roberts said it’s so the mother of four could spend more time with her family. But there are obvious political considerations in cutting Wall Street ties on the cusp of a campaign.

Mary Pat has been the family’s main breadwinner and reported earning more than $500,000 in the couple’s 2013 tax filings.

The Christies have two children in college.
