(CNN) The decision by Bernie Sanders' campaign to immediately engage with Joe Biden -- in a series of public remarks, tweets and emails to supporters -- came from the top, campaign manager Faiz Shakir told CNN on Thursday. A spokesperson for Biden's campaign declined to comment. "On many issues, Vice President Biden has been wrong first," Shakir said. "Since the China trade deal I voted against, America has lost over 3 million manufacturing jobs," Sanders tweeted. Biden's campaign on Wednesday evening sought to clarify his remarks, which drew criticisms from Republicans like Sen. Mitt Romney.
