ST. LOUIS (KTVI) – Democrat presidential candidate Hillary Clinton's St. Louis campaign imported some high-powered help in her bid to win the Missouri Primary.

New Jersey Senator Cory Booker, one of only two African-Americans in the United States Senate is one of the parties rising stars. He spoke to volunteers at the campaign's midtown headquarters Sunday. He also answered a few questions from FOX 2's Elliott Davis.

Booker says he's not surprised by Clinton's spirited battle with Bernie Sanders for the Democrat nomination. He says Clinton knew the race wasn't going to be easy. Still he's confident Clinton will win in the end.

Commenting on the recent troubles at Republican Donald Trump rallies he calls it bad for the nation. Senator Booker was also a key player in President Obama's campaign for the White House.
