Minnesota Sen. Amy Klobuchar (D) was forced to cancel a presidential campaign rally in her home state on Sunday after protesters occupied the stage for over an hour shouting "Black Lives Matter," "Free Myon," and "Klobuchar has got to go."

The rally in suburban St. Louis Park, Minnesota, was supposed to be a homecoming event for Klobuchar ahead of the state's primary vote on Tuesday, but it ended up turning into a nightmare for the candidate.

At least 50 protesters seized the stage before Klobuchar's arrival and demanded that the senator drop out of the presidential race following an Associated Press investigation that questioned Klobuchar's handling of a 2002 case that sent a black teen, Myon Burrell, to prison for life. Klobuchar was the county's top prosecutor at the time.

According to CBS News, the protesters traded chants for over an hour with supporters, who countered with "Amy, Amy" chants of their own.

The video below, posted to Twitter by a local news reporter, shows protesters loudly chanting over supporters as people gathered in a gymnasium for the event. They shouted "black lives matter" and carried a large banner, saying, "Stop Mass Incarceration."

Another video shows the moment that an announcer took to the loudspeaker to report the event was cancelled.

"I'm sorry for any inconvenience, please remember to vote on Tuesday," the announcer can be heard saying.

Klobuchar has struggled to corral support among black Americans in the campaign and this recent clash with protesters will likely only make matters worse as the senator looks to boost her campaign with a win in her home state on Tuesday.

"Amy Klobuchar is not as progressive as she seems," Leslie Redmond, president of the Minneapolis NAACP, told CBS News. "We're talking about someone who wants to be president of the United States, and yet you're from a state that has some of the worst racial disparities in the nation and the lead prosecutor convicting a 16 year old who was innocent of the crime."

Klobuchar has maintained a slight edge in her home state, according to the RealClearPolitics polling average, but Sen. Bernie Sanders (I-Vt.) is within striking distance.

The Minnesota senator has failed to sustain any momentum following her surprising third-place finish in New Hampshire last month. But despite mounting pressure to drop out, she has vowed to stay in the race at least through Super Tuesday.

Update: On Monday, Klobuchar suspended her campaign for president.
