Tammy Murphy, the first lady of New Jersey, has suspended her campaign for U.S. Senate.

She made the announcement in a video posted on social media.

"After many busy, invigorating and, yes, challenging months, I am suspending my Senate campaign today,” she said. “I have been genuine and factual throughout, but it is clear to me that continuing in this race will involve waging a very divisive and negative campaign which I am not willing to do."

Her decision to drop out likely clears the way for Rep. Andy Kim in the Democratic primary on June 4.

“New Jersey's next senator must focus on the issues of our time and not be mired in tearing others down while dividing the people of our party and state,” she said.

Menendez announced that he would not run in that primary but did not rule out seeking reelection as an independent as he faces federal corruption charges.

Murphy, a first-time candidate, was running with the backing of influential Democratic figures. Kim, a three-term congressman, has centered his campaign in part on upending the state’s unique ballot design, widely viewed as favoring candidates preferred by county party insiders.

The stakes are high, with Democrats competing to hold on to their narrow control of the Senate.

Republicans have their own primary unfolding, featuring businessman Curtis Bashaw, Mendham Borough Mayor Christine Serrano Glassner and former News 12 reporter Alex Zdan.
