“Cory Booker, the New Jersey mayor who is a rising star in the Democratic party, filed documents on Friday revealing his intention to run for the U.S. Senate in 2014, possibly setting up a primary challenge against 88-year-old Democratic incumbent Frank Lautenberg
Booker, the 43-year-old mayor of Newark, announced in December he would “explore the possibility” of running for Senate.
Lautenberg has yet to announce his intentions. His press office did not return a call seeking comment on Booker’s filing with the U.S. Federal Election Commission.
Lautenberg, who was diagnosed with a curable form of stomach cancer in 2010, has been senator for all but two years since 1982.
Booker had previously said he was also considering opposing New Jersey Republican Governor Chris Christie in this year’s gubernatorial election, but settled on the Senate option.
