New York City Mayor Bill de Blasio (D), who managed Hillary Clinton's 2000 Senate campaign before he was an elected official, declined to endorse his former boss on Sunday as Clinton prepared to announce a 2016 White House bid.
Asked by "Meet The Press" host Chuck Todd whether he would back Clinton, de Blasio said that he was first waiting to see what kind of agenda the former secretary of state would offer.
"I think like a lot of people in this country, I want to see a vision," de Blasio said. "And again that would be true of candidates on all levels. It's time to see a clear, bold vision for progressive economic change."
Even though he wouldn't offer his endorsement, de Blasio called Clinton a "tremendous public servant" and "one of the most qualified people to ever run" for president.
On Friday, The New York Times reported that Clinton would begin her campaign by slowly offering ideas on how to increase wages and reduce income inequality.
De Blasio -- who was sworn in at his inauguration by former President Bill Clinton -- isn't the first progressive Democrat to hedge on endorsing Hillary. In February, Sen. Elizabeth Warren (D-Mass.), who has urged Hillary Clinton to pursue a White House bid, also said that she was waiting to see what kind of agenda Clinton offered in a presidential campaign.
