WASHINGTON — Senator Dianne Feinstein, Democrat of California, officially declared her intention to run for reelection Monday, ending months of speculation about her future.
The decision averts what would have been an intense scramble of politicians seeking to succeed her.
‘‘I am running for reelection to the Senate. Lots more to do: ending gun violence, combating climate change, access to health care. I’m all in!’’ Feinstein tweeted.
On Sunday, Feinstein hinted in a national television interview that she was likely to run again, telling NBC’s ‘‘Meet the Press’’ that she was close to a formal decision.
Feinstein, 84, is California’s senior senator and the oldest US senator in office. She will be seeking her fifth full term.
In the past week, Feinstein was vaulted again into the spotlight as she renewed her campaign to enact gun control legislation following the deadly shooting rampage in Las Vegas.
Feinstein responded to the Las Vegas shooting by calling for a ban on bump stocks, devices that allow some semiautomatic weapons to mimic an automatic weapon, which are illegal.
