Washington (CNN) Sen. Bernie Sanders on the campaign trail Saturday attacked former New York Mayor Michael Bloomberg, saying "all his money" will not be enough to produce the voter turnout needed to defeat President Donald Trump.

"The simple truth is that Mayor Bloomberg with all his money will not create the kind of excitement and energy we need to have, the voter turnout we must have to defeat Donald Trump," Sanders said Saturday during a dinner in Clark County, Nevada.

Sanders has previously criticized Bloomberg's wealth, but on Saturday, the Vermont senator launched a series of critiques on Bloomberg's policy positions -- from stop and frisk policing to redlining to Bloomberg's record on taxing the wealthy, social security and raising the minimum wage.

"Let me also say a word to you about the current campaign and to say that regardless of how much money a multi-billionaire candidate is willing to spend on his election we will not create the energy and excitement we need to defeat Donald Trump if that candidate pursued advocated for, and enacted racist policies, like stop and frisk, which caused communities of color in his city to live in fear," Sanders said.
