"Things are changing swiftly and dramatically in this country, and I have faith that something is awakening among us," Williamson wrote. "A politics of conscience is still yet possible. And yes… love will prevail."
Williamson is the second Democratic presidential hopeful to end a bid for the White House in 2020. Last week, former Housing and Urban Development Secretary Julian Castro announced his exit from the race. Sen. Kamala Harris, D-California, former U.S. congressman Joe Sestak and Montana Gov. Steve Bullock suspended their campaigns in December.
Thirteen candidates remain in the race for the 2020 Democratic presidential nomination.
