Bernie Sanders signaled Wednesday that he was open to ending his presidential run after another round of landslide losses to Joe Biden, and new signs emerged of communication between the two camps as some Democrats hoped for a swift end to a bruising primary.

Sanders campaign officials said the senator from Vermont planned to leave Washington and return home, where he and his wife, Jane, would talk to supporters and determine the future of his presidential run. The campaign also suspended its Facebook ads and, uncharacteristically, made no request for donations in an email to backers updating them on the situation.

Biden deputy campaign manager Kate Bedingfield said that aides to the two candidates have been in touch regularly to discuss the public health crisis that has gripped the country, disclosing talks that could form the basis of a broader agreement on policies and might make Sanders more comfortable leaving the race.

The two campaigns “have been in regular contact at a senior level” since last week to discuss how the coronavirus pandemic is affecting the campaigns, Bedingfield said in a statement to The Washington Post, “as well as to discuss both Vice President Biden’s and Senator Sanders’ ideas on policy responses to the virus.”
