After being criticized for her remarks about George Floyd "sacrificing" his life "for justice," House Speaker Nancy Pelosi (D-Calif.) tried again on Twitter.

"George Floyd should be alive today," Pelosi tweeted on Tuesday evening. "His family's calls for justice for his murder were heard around the world. He did not die in vain. We must make sure other families don't suffer the same racism, violence, and pain, and we must enact the George Floyd Justice in Policing Act."

Pelosi appeared at a press conference with the Congressional Black Caucus shortly after former Minneapolis police officer Derek Chauvin was found guilty of murdering Floyd, a 46-year-old unarmed Black man. Floyd's death gained worldwide attention, sparking global protests against police brutality, and during her remarks, Pelosi thanked Floyd "for sacrificing your life for justice." She added that because of him and "millions of people around the world who came out for justice, your name will always be synonymous for justice." Catherine Garcia

Homeland Security Secretary Alejandro Mayorkas announced Sunday that four migrant families separated at the border in late 2017 will be reunited this week, the first fruits of President Biden's Family Reunification Task Force. The first two reunions took place Tuesday — a Honduran mother surprising her two sons in Philadelphia after more than three years of separation and a Mexican mother reunited with her son in California after nearly four years. ABC News documented the emotional reunions on Wednesday's World News Tonight.

Former President Donald Trump enacted an official policy of separating children from their parents at the border from April to June 2018, but it later emerged that the Trump administration had been regularly separating families for much of 2017. A federal judge ordered the Trump administration to reunite the families by August 2018, and hundreds of parents were rejoined with their children, but many more had been deported with little or no information on how to contact them.

Of the more than 5,500 children separated from the parents under Trump, more than 1,000 are still separated, the Biden administration estimates. Lawyers and advocacy groups working to reunited the families say 465 parents have not been located.

It isn't clear what will happen to the parents reunited with their children. The Biden administration is allowing them into the U.S. on humanitarian parole while longer-term solutions are explored. The administration's Family Reunification Task Force worked with lawyers and advocates to select 36 families for a trial run, meant to pave the way for hundreds more reunifications.

Sandra Ortiz, separated from her son Bryan Chavez in October 2017, learned last week that she would be flown to the San Ysidro port of entry to be reunited with her son. They had fled to the U.S. from Michoacán after cartels murdered Ortiz's husband, dismembered their teenage neighbor, and began recruiting Chavez, The Washington Post reports. After they requested asylum at the San Ysidro border crossing, "they told me to say goodbye to my son, that I wouldn't see him again," Ortiz says. "And then they took him away." Ortiz was detained for more than a month, told her son would be put up for adoption, then deported. Chavez has been living with relatives in California. Peter Weber

The Justice Department's Civil Rights Division sent a letter to Arizona Senate President Karen Fann (R) on Wednesday detailing concerns it has over private contractors performing an audit of the November presidential election in Maricopa County.

Last month, the GOP-controlled state Senate used subpoenas to get the 2.1 million ballots cast in Maricopa County during the election, as well as voting machines and private and public voter information. The Senate hired private contractors to conduct the audit, now underway in Phoenix, seeking a recount of all ballots and a review of the voting machines and voter information to search for evidence of potential fraud, The Arizona Republic reports.

The main contractor is Cyber Ninjas, a cybersecurity firm based in Florida whose CEO spread "Stop the Steal" conspiracy theories ahead of the Jan. 6 Capitol riot. The Arizona Democratic Party and Maricopa County Supervisor Steve Gallardo filed a lawsuit to try to stop the audit, saying it lacked transparency and clear procedures on how to protect the ballots, and several civil rights organizations have asked the Justice Department to send federal monitors to Phoenix to oversee the audit.

The letter from the Justice Department to Fann was sent by Pamela Karlan, the principal deputy assistant attorney general in the Civil Rights Division. She said the DOJ is concerned about reports that the ballots, voting machines, and voting information are not secure and at risk of being "lost, stolen, altered, compromised, or destroyed." Additionally, in its work plan, Cyber Ninjas told the Senate it will contact voters via phone and in person to "collect information on whether the individual voted in the election." This could be seen as voter intimidation, Karlan wrote, which is illegal.

Karlan asked Fann to respond with "the steps that the Arizona Senate will take to ensure that violations of federal law do not occur" during the audit. Fann told The Arizona Republic the Senate's attorney is working on a response to Karlan. Catherine Garcia

SpaceX's Starship rocket prototype had its first successful test flight on Wednesday, touching down safely in south Texas after flying more than six miles over the Gulf of Mexico.

The 160-foot rocket is made of stainless steel and bullet shaped. Four earlier test flights of Starship prototypes all ended with explosions taking place either before, during, or immediately after landing, The Associated Press reports. SpaceX aims to use Starship to transport astronauts to the moon and people to Mars. Catherine Garcia

With highly-transmissible variants spreading across the state and more kids taking part in face-to-face activities, children now make up 26.4 percent of all active COVID-19 cases in Colorado.

Children between 0 to 19 make up 16.57 percent of overall infections in Colorado since the start of the pandemic, ABC News reports; 847 kids have been hospitalized with COVID-19 and 13 have died. Dr. Sean O'Leary of the University of Colorado School of Medicine told the network that since children under 16 aren't eligible for any COVID-19 vaccines, "that's a group that is completely prone to getting infected at this point."

Last week, there were 210 active outbreaks at schools in Colorado, the highest number since early December, when there were 211 outbreaks, the Denver Post reports. There are four variants in Colorado, and 49 percent of all cases in the state are of the highly-contagious B.1.1.7 variant that was first identified in the United Kingdom.

Nationwide, more than 3.78 million children have tested positive for COVID-19, about 13.8 percent of all reported cases. Catherine Garcia

Two college students from California were found guilty on Wednesday of killing an Italian policeman in 2019 and sentenced to life in prison.

Finnegan Lee Elder, 21, and Gabriel Natale-Hjorth, 20, were accused of stabbing to death 35-year-old Vice Brig. Mario Cerciello Rega while they were vacationing in Rome. On the night of July 25, the men — friends from high school — had been ripped off by a drug dealer, and they stole the backpack of a middleman who gave them an over-the-counter pain medicine instead of cocaine. Elder and Natale-Hjorth set up a meeting to give the man his backpack in exchange for their money, but instead encountered Cerciello Rega and his partner, Andrea Varriale.

Elder said he thought Cerciello Rega was a drug dealer who was trying to "strangle or choke me," but Varriale testified that both officers showed Elder and Natale-Hjorth their badges. Cerciello Rega was stabbed 11 times, and Varriale said that blood was pouring out of his body like "a fountain."

In a statement, Elder apologized to Cerciello Rega's family and friends, adding that if he could "go back and change things, I would do it now, but I can't." Elder's attorney, Renato Borzone, has promised to appeal, saying it is "unheard of" to give two young men life sentences. "Italy's justice is strong with the weak, and weak with the strong," Borzone added. Catherine Garcia

The Republican Party is at a turning point, Rep. Liz Cheney (R-Wyo.) writes in an opinion article published in The Washington Post on Wednesday evening, and members must "decide whether we are going to choose truth and fidelity to the Constitution."

Cheney is receiving backlash from the GOP for voting to impeach former President Donald Trump for his role in inciting the Jan. 6 Capitol riot, as well as pushing back against his false claims of election fraud. Trump, she writes, is "seeking to unravel critical elements of our constitutional structure that makes democracy work — confidence in the result of elections and the rule of law. No other American president has ever done this."

Cheney, the No. 3 House Republican, called herself a "conservative Republican," and said the "most conservative of conservative values is reverence for the rule of law." The Electoral College "has spoken," she added, and "more than 60 state and federal courts have rejected the former president's arguments, and refused to overturn election results. That is the rule of law; that is our constitutional system for resolving claims of election fraud."

Republicans now have to decide whether to join "Trump's crusade to delegitimize and undo the legal outcome of the 2020 election, with all the consequences that might have," Cheney said. He has "never expressed remorse or regret for the attack of Jan. 6 and now suggests that our elections, and our legal and constitutional system, cannot be trusted to do the will of the people," she continued. "This is immensely harmful, especially as we now compete on the world stage against Communist China and its claims that democracy is a failed system."

The path forward is clear, Cheney said. Republicans need to back the Justice Department's criminal investigations of the Jan. 6 attack, support a bipartisan review by a commission with subpoena power, and "stand for genuinely conservative principles, and steer away from the dangerous and anti-democratic Trump cult of personality." Trump is trying to "undermine the foundation of our democracy," Cheney said, and with history and our children watching, "we must be brave enough to defend the basic principles that underpin and protect our freedom and our democratic process."
