The death of George Floyd, a black man who died on Memorial Day after he was pinned down by a white Minnesota police officer, has sparked outrage and protests in Minneapolis, across the United States and across the world.
Second-degree murder, third-degree murder and manslaughter charges have been filed against Derek Chauvin, the ex-officer who prosecutors say held his knee on Floyd's neck for nearly nine minutes. The three other officers have been charged with aiding and abetting second-degree murder and aiding and abetting manslaughter. All four officers have been fired.
Governors in 32 states and Washington, D.C., have activated more than 32,400 members of the National Guard.

3:14 p.m.: NYC Health Department shares tips on how to safely protest amid COVID
The New York City Health Department has released tips for how to safely protest during the COVID-19 pandemic.
The department noted that it's still recommending to avoid large gatherings.
However, if one is planning on to go out, officials recommend the following: Wear a face covering and make sure it fully covers your nose, mouth and chin; carry only what you need ( including goggles, hand sanitizer, your own water bottle, snacks, an ID, any medication you may need); carry saline in a squirt bottle; go with a small group; and have a plan for safely exiting.
Once at the protest, the department recommends using noisemakers, drums or written signs to protest rather than shouting, which could possibly increase exposure. The NYC Health Department also recommends maintaining as much physical distance as possible between you and those not in your group, practicing healthy hand hygiene, not sharing water bottles or megaphones, and being aware of both your physical and mental health.
Upon returning, immediately wash your hands with soap and water for at least 20 seconds and assume you have been exposed to COVID-19 so avoid contact with others, particularly those over 50 or who have a serious health condition.

6:10 a.m.: Trump retweets video attacking George Floyd
Hours after saying he hoped George Floyd was looking down "from heaven" and saying, "This is a great thing happening for our country," in regards to May's unemployment numbers, President Donald Trump retweeted a video that attacked Floyd's character.
The video clip was from conservative radio host Glenn Beck.
"I don't care WHAT George Floyd did. The officer should have never treated him like that and killed him! But we still must ask: Is he a HERO?" Beck tweeted.
In the clip that Trump retweeted, Beck and conservative commentator Candace Owens attack Floyd's character, bring up his alleged criminal background and question why people are using his death as a call to action for social justice.
"This is a guy with a very long record and a very long criminal record," Beck said. "He was said to be cleaning up his life by his family, I hope that was true. Is this really the guy that black America ... is this the symbol of black America today?"
"Yes," Owens responds. "The fact that he has been held up as a martyr sickens me."
She said he's a symbol "of the broken culture of black America today ... George Floyd was not a good person."
4:53 a.m.: Judge orders Denver PD to limit chemical use in protests
A federal judge ruled Friday that the Denver Police Department must scale back its use of chemicals and projectiles in protests.
Judge R Brooke Jackson of U.S. District Court, District of Colorado, said some actions of "what I hope and believe to be a minority of the police officers in Denver and the nation during recent days (and before) not only vis a vis persons of color but against peaceful protesters of all backgrounds have been disgusting."
Jackson ruled that tear gas and non-lethal projectiles can only be used after a supervisor at the rank of Captain or above at the scene "specifically authorizes such use of force in response to specific acts of violence or destruction of property that the command officer has personally witnessed."
The court's ruling also said that projectiles may never be shot toward the head, pelvis or back and that they are not to be shot indiscriminately into a crowd.
"Although I do not agree with those who have committed property damage during the protests, property damage is a small price to pay for constitutional rights—especially the constitutional right of the public to speak against widespread injustice," Jackson wrote in his ruling. "If a store's windows must be broken to prevent a protestor's facial bones from being broken or eye being permanently damaged, that is more than a fair trade. If a building must be graffiti-ed to prevent the suppression of free speech, that is a fair trade. The threat to physical safety and free speech outweighs the threat to property."
Additionally, all officers deployed to demonstrations must have their body cameras worn at all times and must not intentionally obstruct the camera from recording.
The judge's ruling, according to ABC affiliate KMGH in Denver, came after four residents filed a lawsuit against the city of Denver, claiming police officers violated protesters' constitutional rights. They also asked the judge to temporarily halt the use of tear gas, pepper balls, spray and other non-lethal projectiles.
Denver PD said it would comply with the judge's ruling and that most of the orders are in line with department policy already.
"A federal judge issued a Temporary Restraining Order (TRO) clarifying #DPD use of non-lethal dispersant devices," the department said in a statement. "In the meantime, we will comply with the judge's directions, many of which are already in line with our community-consulted Use of Force Policy."
