Three anonymous sources close to the Democratic Party have told the Washington Post that Senator Bernie Sanders had urged presidential candidate Joe Biden to campaign on expanded healthcare coverage, jobs and wages.

According to the report, Faiz Shakir, Sanders’ campaign manager during his failed bid for the Democratic nomination, insisted the Vermont senator was “working as hard as he can” to get Biden elected in November.

But while claiming Biden was “in a very strong position” to win, Shakir admitted Sanders “feels there are areas the campaign can continue to improve upon.”

“He has been in direct contact with the Biden team and has urged them to put more emphasis on how they will raise wages, create millions of good-paying jobs, lower the cost of prescription drugs and expand health care coverage,” the spokesman said.

Sanders, campaigning on a radical ‘democratic socialist’ platform, lost out to former vice-president Biden in this year’s Democratic primaries, just as he did to Hillary Clinton in 2016. Clinton went on to lose to Trump despite opinion polls consistently putting her in the lead.
