Democratic Rep. Jacky Rosen (Nev.) has unseated incumbent Sen. Dean Heller (R-Nev.), in the first Senate pickup for Democrats during a tough night. Heller conceded the race after CNN and other news organizations projected Rosen's victory.

This had been one of the most closely watched races of 2018, and Heller was widely considered the most vulnerable Republican senator in the country. Hillary Clinton carried Nevada in 2016, and he just barely won his first term in 2012 by about 1 percentage point. With Rosen victorious, Nevada becomes the seventh state historically and fifth state currently to be represented by two female senators, as Rosen noted in her victory speech. Peter Weber

About 60 million Americans were under curfew in 200 cities on Tuesday night, the eighth day of protests sparked by the police killing of George Floyd. Thousands turned out in Washington, D.C, and hundreds stayed out after the 7 a.m. curfew, which federal and military police spread throughout the capital did not enforce, The Washington Post reports. Many showed up for the first time in response to Monday night's crackdown.

In New York City, thousands remained out after the 8 p.m. curfew, but throughout the U.S. things appeared to be calmer than on previous nights. Journalists are exempt from New York City's curfew, but New York Police officers surrounded two Associated Press reporters just after 8 p.m Tuesday night and shoved and screamed profanities at them until they left. Videojournalist Robert Bumsted, documenting the protests in lower Manhattan with photographer Maye-E Wong, captured some of it on video.

Both journalists were wearing AP identification and told police they were media, and Bumsted reminded one officer screaming at him that journalists are "essential workers" who are legally allowed to be out after curfew. "I don't give a s--t," one officer said. "Essential to who?" another yelled. "Who are you essential to? Who are you essential to?! Get back!" Still another cop tells Bumsted to "get the f--- out of here you piece of s--t." They separated Wong and Bumsted and only allowed them to reunite when Bumsted said Wong had the keys to his car.

NYPD officials told AP the department would "review this as soon as possible." AP spokeswoman Lauren Easton said journalists "report the news on behalf the public" and "it is unacceptable and deeply troubling when journalists are harassed simply for doing their job." Police in other cities have shot reporters with pepper balls and rubber bullets, gassed them, arrested them, and otherwise harassed them for no evident reason. Peter Weber

"For a week, America's streets have been filled with protesters enraged over the murder of George Floyd by police," Stephen Colbert said on Tuesday's Late Show, and Monday evening President Trump "finally appeared in the Rose Garden to calm a troubled nation — by threatening martial law." Responding to protests about police brutality by "threatening to send in the Army to crush them," he said, is "like forgetting your child's birthday and apologizing by sending in the Army to crush them."

Trump wanted to end his speech with a stroll to St. John's Church, Colbert said, but "there was a crowd of peaceful protesters in the way. So he had military police open fire with rubber bullets, flash grenades, and tear gas," and "once the path was cleared for Caesar's brave shamble, Trump made his way across the street to the boarded-up church, where he, with visible confusion and discomfort, groped a Bible" for the cameras.

Tooning Out the News had God deal with Trump's photo op.

Trump has always been "an armchair thug who glorifies violence," but his Rose Garden speech and its aftermath "was one of the most menacing moments" of his presidency, Late Night's Seth Meyers said. We're at the "worst-case scenario where our democracy crumbles and our country descends into authoritarianism," he added. "There's no on-off switch. Democracy, it turns out, is on a dimmer."

Yes, "our president, if we can still even call him that, seems to believe he is the warden overseeing a prison break," Jimmy Kimmel said. "This is a week that any other president would have gone on TV and at least tried to bring us together," but Trump "can't even go through the motions."

"Mr. Tough Guy was whisked into a panic bunker on Friday as crowds assembled outside the White House — it took three-and-a-half years, he finally got that massive crowd to show up for him in D.C.," Kimmel joked wryly. "And the reports that he was holed up and hiding must have really gotten under that orange skin," because he had Attorney General William Barr gas protesters so he could go outside and hold "a Bible upside-down in front of a church." He ended by trying to explain white privilege for people who, like him, were skeptical: "White privilege doesn't mean your life hasn't been hard, it just means the color of your skin isn't one of the things that makes it harder."

Stephen Wamukota's ingenuity has earned him a presidential award.

Wamukota, 9, lives in western Kenya, and received the honor after creating a wooden hand-washing machine that uses a foot pedal to dispense water so people can avoid touching surfaces amid the coronavirus pandemic. He started working on his invention after watching a television show about the virus, and has already made two hand-washing stations.

His dad, James Wamukota, told BBC News he had purchased pieces of wood to make a window frame, "but when I came back home after work one day, I found that Stephen had made the machine. The concept was his and I helped tighten the machine. I'm very proud."

On Monday, Wamukota and 67 other Kenyans received inaugural Presidential Order of Service, Uzalendo (Patriotic) Awards, with Wamukota the youngest winner. This made him "very happy," he told BBC News. His dream is to become an engineer, and his county's governor has already promised to give Wamukota a scholarship. Catherine Garcia

Ella Jones made history on Tuesday night, becoming the first black mayor of Ferguson, Missouri.

Jones, who has served as a council member for five years and is a 40-year resident of Ferguson, is also the first woman to be elected mayor of the city.

In August 2014, Darren Wilson, a white Ferguson police officer, fatally shot Michael Brown, an 18-year-old unarmed black man, triggering unrest in the city and protests across the country. This weekend, there were demonstrations in Ferguson over the death of George Floyd, an unarmed black man who died last week after a white police officer knelt on his neck for several minutes.

Protesters peacefully marched with the Ferguson police chief, but there was also some violence and looting, and Jones said as mayor she will "help stabilize the businesses in Ferguson" that were damaged. She told the St. Louis Post-Dispatch it is "just my time to do right by the people," and when asked what her election means for black residents, she responded, "One word: Inclusion."

Nine-term Republican Rep. Steve King (Iowa), stripped of his committee assignments in 2018 after questioning why white nationalism is bad, lost his Republican primary on Tuesday night to state Sen. Randy Feenstra (R). King, a hardline conservative, has a long history of making controversial and incendiary remarks about immigrants, Muslims, and other issues, but his former supporters in Iowa's 4th Congressional District jumped ship after he was booted off the House Agriculture Committee, and to a lesser extent the Judiciary Committee.

"I personally feel very let down about some of the things that have happened because we need someone who is strong in agriculture from this area," state Sen. Annette Sweeney, who shifted support from King to Feenstra, told The Associated Press. King claimed House Minority Leader Kevin McCarthy (R-Calif.) had pledged to support reinstating his committee assignments after the election, but McCarthy dismissed the claim. Feenstra's campaign was bankrolled by an array of conservative groups, including National Right to Life and the U.S. Chamber of Commerce. Republicans had warned that King might lose.

Iowa Democrats selected Des Moines businesswoman Theresa Greenfield as their nominee to take on Sen. Joni Ernst (R) in what could end up being a competitive race. Greenfield, 55, raised $7 million, much more than her three Democratic opponents. Peter Weber

David Dorn, a 77-year-old retired police captain, was shot and killed by looters early Tuesday in St. Louis, with the shooting broadcast on Facebook Live.

Dorn died on the sidewalk outside of Lee's Pawn & Jewelry after being shot in the torso. His wife, Ann Marie Dorn, told the St. Louis Post-Dispatch that the pawn shop was owned by one of her husband's friends, and he would go down to the store when its burglar alarms would go off. Police said they do not have any suspects, and are offering a $10,000 reward for information leading to an arrest.

Dorn was a police officer in St. Louis for 38 years, retiring in 2007, and later served as police chief in Moline Acres. The Ethical Society of Police said he was "the type of brother that would've given his life to save them if he had to."

Facebook briefly took the shooting video down, but said in a statement it was put back up as it did not expressly violate company policy on graphic or violent content. "Under our policies, the video has been covered with a warning screen but remains on the platform so that people can raise awareness or condemn this event," a spokesperson said. One person who watched it was state Rep. Rasheen Aldridge (D), who told the Post-Dispatch he was "very traumatized." Catherine Garcia
