Vaccines work, and Twitter wants you to know it.

Amid growing misinformation surrounding vaccines, Twitter has rolled out a tool that combats falsities with reliable information, it announced Friday. The tool drops a link to vaccines.gov at the top of U.S. searches for tweets related to vaccines, and links out to appropriate government information for Canada, Japan, Brazil, and several other countries.

In the past few months, the U.S. has seen the number of measles outbreaks skyrocket, putting it on track for the highest annual number of measles cases since the disease was declared "eliminated" in 2000. That's partially been furthered by people who choose not to vaccinate themselves or their children, and who often chalk their decisions up to false associations between vaccines and autism. Conspiracy theorists and even the president have spread this misinformation, and it has proliferated widely on social media as well.

That's why Twitter on Friday quietly unveiled its small addition to its search function, which puts reliable information on top of anything questionable. Twitter also said it won't "auto-suggest queries that are likely to direct individuals to non-credible commentary and information about vaccines" in its blog post. It already works to ensure advertisements don't "contain misleading claims about the cure, treatment, diagnosis, or prevention of certain diseases and conditions," the post continues.

The move is similar to how Twitter offers resources when someone searches for tweets related to suicide or self-harm. It also has a reporting feature so users can notify a team that reviews mentions of self-harm or suicide on the site. Kathryn Krawczyk

The Senate Judiciary committee has come to a bipartisan conclusion after the death of George Floyd.

After "the horrific death of George Floyd while in police custody in Minneapolis," the Senate Judiciary committee will conduct a hearing on police use of force, committee chair Sen. Lindsey Graham (R-S.C.) announced Friday. Both he and Ranking Member Dianne Feinstein (D-Calif.) "are appalled at what we saw," and will hold the hearing to "shine a bright light on the problems associated" with Floyd's death "with the goal of finding a better way forward for our nation."

Earlier Friday, Sen. Amy Klobuchar (D-Minn.), the former lead prosecutor for Minneapolis' Hennepin County, told MSNBC's Andrea Mitchell she would use her spot on the Judiciary Committee to push for "systematic change to our criminal justice system in Minnesota and across the country."

President Trump gave a Friday press conference that didn't even touch that day's biggest topic.

On Friday, Trump announced that he was withdrawing U.S. support from the World Health Organization, reshuffling America's $450 million annual contribution to the WHO to other health groups. Trump went on to criticize China for allegedly covering up the beginnings of the coronavirus pandemic, and claimed the WHO had allowed that cover-up to happen.

While Trump had previously praised China for its "transparency" during the COVID-19 crisis, on Friday he suggested a unfounded conspiracy in which the coronavirus "didn't go to Beijing." Trump then noted that China gives $40 million to the WHO compared to the U.S.'s $450 million, but claimed without proof that the organization is controlled by China. The move leaves the WHO without its largest financial backer, The Associated Press reports.

Trump left the conference without taking any questions from the press, which would've presumably been about the ongoing protests in Minneapolis over George Floyd's death in police custody. Trump had tweeted "when the looting starts, the shooting starts," a phrase that some critics linked to a racist Miami police chief who invoked it when cracking down on black neighborhoods in the 1960s.

The family of George Floyd is demanding stronger charges for the former Minneapolis police officer arrested Friday in connection with Floyd's death. Derek Chauvin received third-degree murder and manslaughter charges, despite evidently ignoring police training that would have taught that restraining a person in such a way as he did Floyd is "inherently dangerous," according to the criminal complaint.

"We want a first-degree murder charge," the family's statement said. "And we want to see the other [three] officers arrested. We call on authorities to revise the charges to reflect the true culpability of this officer."

The disturbing complaint describes how Chauvin placed "his left knee in the area of Mr. Floyd's head and neck. Mr. Floyd said, 'I can't breathe' multiple times and repeatedly said 'Mama' and 'please' as well. The defendant [Chauvin] and the other two officers stayed in their positions."

Floyd then stopped breathing or speaking. One of the officers checked his pulse and said "I couldn't find one," but Chauvin did not remove his knee for several more minutes. An ambulance eventually arrived; Floyd was pronounced dead at the hospital.

Floyd's family is seeking an independent autopsy after the initial examination "revealed no physical findings that support a diagnosis of traumatic asphyxia or strangulation" and said Floyd's "underlying health conditions including coronary artery disease and hypertensive heart disease" could have contributed to his death while under police restraint. The report adds that "the defendant had his knee on Mr. Floyd's neck for 8 minutes and 46 seconds in total. Two minutes and 53 seconds of this was after Mr. Floyd was non-responsive." Jeva Lange

President Trump on Friday attempted to clean up his recent comments about the protests in Minneapolis that Twitter said violated its rules but surprisingly left a subsequent event without addressing the situation at all.

Trump in a late-night tweet commented on the protests in Minneapolis over the death of George Floyd, saying he may have the National Guard "assume control" and writing, "when the looting starts, the shooting starts," a message that Twitter attached a warning label to saying it violated its rules against glorifying violence. On Friday afternoon, Trump claimed that he meant to say that "looting leads to shooting" but that "I don't want this to happen," confusingly adding that this was "spoken as a fact, not as a statement."

The president shortly after spoke at a supposed news conference in the Rose Garden, and aides had said plans were in place for him to address the protests in Minneapolis, CNN's Sarah Westwood reports. Instead, he left without answering a single question or addressing Minneapolis at all, and Westwood writes it "remains unclear" why the plans apparently changed. PBS News' Yamiche Alcindor described seeing Trump leave without talking about the situation Minneapolis as "stunning." Brendan Morrow

Derek Chauvin, the former Minneapolis police officer who was arrested in connection with the death of George Floyd, has now been charged with murder.

Prosecutors on Friday announced that Chauvin, who was fired after he was filmed kneeling on Floyd's neck for almost 10 minutes while Floyd said that he couldn't breathe, has been charged with third-degree murder and manslaughter. The charges were unveiled shortly after Chauvin's arrest was announced and four days after Floyd's death, which has sparked nationwide outrage and protests.

Hennepin County Attorney Mike Freeman in a press conference said this is "by far the fastest we've ever charged a police officer."

"We can only charge a case when he have sufficient, admissible evidence to prove the case beyond a reasonable doubt," he said. "As of right now, we have that."

An investigation into the other officers involved in the incident is ongoing, Freeman said, adding that "I anticipate charges." A complaint is being processed and will be released later today.

Shortly after the charges were announced, Attorney General William Barr said in a statement that the Department of Justice is "conducting an independent investigation to determine whether any federal civil rights laws were violated," saying "I am confident justice will be served." Brendan Morrow

Sen. Amy Klobuchar (D-Minn.) has responded to criticism of her time as Minneapolis' top prosecutor.

Before she was elected to the U.S. Senate in 2006, Klobuchar was the Hennepin County attorney in Minnesota, in charge of prosecution for the state's most populous county. Reports have indicated Klobuchar did not go after numerous police officers who shot civilians, and when MSNBC's Andrea Mitchell asked her about that on Friday, Klobuchar described her decisions as routine procedure, but also expressed regret for how she handled those cases.

"When I was county attorney, cases we had involving officer-involved shootings went to a grand jury. I think that was wrong now," Klobuchar said. "It would have been much better if I took responsibility and looked at cases and made a decision myself." Still, Klobuchar maintained that "we did not blow off these cases. We brought them to a grand jury, presented the evidence for a potential criminal prosecution, and the grand jury would come back with the decision."

Klobuchar also addressed a 2006 shooting that involved former Minneapolis police officer Derek Chauvin, who was arrested Friday after kneeling on the neck of George Floyd, who later died. Klobuchar was elected to the Senate a week after Chauvin was implicated in the shooting of a suspect who was allegedly attacking police, and left her attorney position just a few months into an investigation into the incident. She said it's "absolutely false" that she declined to prosecute the case involving Chauvin, describing it as a case handled by her successor that a grand jury later declined to prosecute.

Klobuchar went on to call for "systematic change" following Floyd's death both in Minnesota and "across the country." Kathryn Krawczyk
