Republicans have sharpened their attacks on Minnesota Governor Tim Walz over his response to the mass protests that erupted in his state after the 2020 police killing of George Floyd.
As the governor kicks off his campaign as Kamala Harris's running mate, his critics have accused him of bungling the response to the violence by being slow to deploy the National Guard.
At least two people were killed and over 600 arrested during the protests, which caused hundreds of millions of dollars in damages across Minnesota.
The Governor recently defended his actions, saying that his administration tried to do the best it could in a difficult situation.
Floyd's death at the hands of Derek Chauvin, a white Minneapolis police officer, sparked days of protests, some of which descended into riots and looting.
The unrest quickly overwhelmed local authorities, prompting Minneapolis mayor Jacob Frey to request Mr Walz to deploy the National Guard two days after Floyd's death on 25 May in 2020.
A separate written request for 600 troops came just hours later from the city's police chief.
But it was not until 28 May - three days into the violence - that Mr Walz signed an executive order activating Minnesota's National Guard, citing "extensive damage to private property" and a "dangerous situation" for protesters and first responders.
While some troops were deployed that night, they were mostly tasked with protecting federal buildings and were unable to prevent riots which saw a local police station set ablaze.
"We were abandoned," an unnamed local official told an external review of the state's response prepared for Minnesota's Department of Public Safety in 2022. "By the time the National Guard even came, mostly everything had quieted down."
A separate report put together by the then-Republican controlled Minnesota Senate in October 2020 said that Mr Walz "had the ability and duty to use force and law enforcement to stop violence, but he did not".
Criticism of the governor's handling of the protests in the summer of 2020 has re-emerged as an attack line from Republicans following the announcement that Mr Walz would be joining the Harris campaign.
At a rally just hours after the news, Republican vice-presidential hopeful JD Vance, questioned whether "black business owners in Minneapolis are grateful" that Mr Walz "allowed rioters to burn down their business".
The OceanNewsUK has contacted the governor's office for comment.
Mr Walz has said the city's mayor did not give him adequate information to provide the soldiers a mission at that time.
“Decisions were made in a situation that is what it is,” Mr Walz said at a news conference earlier this month. “And I simply believe that we tried to do the best we can in each of those.”
How did Tim Walz respond to Floyd’s death?
The reality of the situation on the ground in May 2020, experts note, was both complex and confusing.
"When everything was unfolding that summer, Minneapolis city leaders were not familiar with the process for asking for the National Guard's help," Duchess Harris, a professor of American Studies at Minnesota's Macalester College who focuses on African-American political history and human rights, told the OceanNewsUK.
"It was unprecedented," added Ms Harris, who was appointed by Mr Walz to be on Minnesota's board of public defence.
Several after-action assessments of the response to the riots also highlight communications breakdowns between city and state officials.
One review, published by the city of Minneapolis in 2020, found that city officials failed to go through proper channels when they requested help.
Instead, they contacted Mr Walz directly to ask him to deploy troops.
"Governor Walz is a 24-year veteran of Minnesota's National Guard," Ms Harris added. "He pushed the mayor of Minneapolis for details. That was his job."
The subsequent activation of Minnesota's National Guard was the largest since the Second World War.
At the time of their deployment, then-President Donald Trump tweeted that "when the looting starts, the shooting starts".
Michelle Phelps, a sociology professor at the University of Minnesota and the author of a book that examined the protest, told the OceanNewsUK that a more forceful response could have inadvertently backfired as authorities sought to control the protests.
"There's a vision in which if we had had a more conservative governor that escalated the state response in the way that President Trump wanted, we would have seen more violence and more destruction," she said.
Some advocates - including civil rights leader Al Sharpton - have also praised Mr Walz's handling of the aftermath and credited him for addressing issues of social justice and police brutality.
Mr Walz was re-elected as Minnesota's governor in 2022, two years after the protests.
While both Ms Harris and Ms Phelps said they expect Republicans to continue to attack Mr Walz for his handling of the protests, neither expect the issue will create a political liability for the governor among undecided voters.
"It's not surprising that Republicans are using this line of attack. It highlights that there are just not that many weaknesses of Walz to attack," Ms Phelps said.
"I don't think it's going to be particularly effective or decisive," she added.
