Sen. Cory Booker announced Monday he is dropping out of the race for the 2020 Democratic presidential nomination.
In an email to his supporters, Booker cited a number of reasons: most notably, a lack of money to continue.
"Our campaign has reached the point where we need more money to scale up and continue building a campaign that can win — money we don't have, and money that is harder to raise because I won't be on the next debate stage and because the urgent business of impeachment will rightly be keeping me in Washington," Booker wrote.
