Sen. Bernie Sanders (I-Vt.) will spend coming days talking to supporters to “assess his campaign,” his campaign manager said Wednesday following decisive victories Tuesday by former vice president Joe Biden in Florida, Illinois and Arizona that gave him firm control of the Democratic nominating contest.

In an email to supporters, Sanders campaign manager Faiz Shakir said there was “no sugarcoating” the results and that Sanders planned to head back to his home state of Vermont after a Senate vote Wednesday. The email did not include a solicitation for campaign donations.

With Biden widening his delegate lead, Sanders is facing growing calls to suspend his campaign. And with more states postponing their primaries due to health concerns, the candidates are facing a hiatus in voting for at least a few weeks — and possibly much longer. The final primaries now could come only weeks before the Democratic National Convention is scheduled to convene in July in Milwaukee — if it is held as planned.
