US Sen. Amy Klobuchar will end her presidential bid and endorse Joe Biden, a campaign aide tells CNN.

       Her path to the nomination all but closed after she posted sixth-place finishes in Nevada and South Carolina, a sign that the Minnesota senator's surprising showing in New Hampshire would not be nearly enough to propel her toward the Democratic nomination.

       Klobuchar, a three-term senator, announced her presidential bid at a snowy, freezing outdoor event in February 2019. She cast herself as the product of working-class roots who could win bipartisan support and help Democrats win back the Midwestern cities and towns that drifted toward Donald Trump in 2016.

       "I don't have a political machine. I don't come from money," Klobuchar told the crowd. "But what I do have is this: I have grit."
