Mayor de Blasio continued his presidential campaign out west today, meeting with labor leaders in Los Angeles.

The mayor was in Las Vegas yesterday, where 18 other Democratic candidates attended a labor union event.

The group included former Vice President Joe Biden, who de Blasio spent a considerable amount of time attacking in last week's debates.

Workers’ rights have been a focal point of the mayor's White House bid.

He's expected to travel to Washington D.C. later today, before returning to the city tomorrow night.
