Booker, who recently announced he had surpassed his fourth-quarter fundraising goal, said his operation would not have the money “to scale up and continue building a campaign that can win,” particularly with a Senate impeachment trial looming and because he would be absent from Tuesday’s debate.

“So I’ve chosen to suspend my campaign now, take care of my wonderful staff, and give you time to consider the other strong choices in the field,” Booker wrote in a message to supporters Monday morning.

On the campaign trail, Booker preached the power of empathy, saying he would beat Trump with love. In his parting message, Booker doubled down on that message.
