President Trump's defense team will wage its second day of arguments in his Senate impeachment trial on Monday, explaining to the Republican-controlled chamber why it should acquit Trump on both impeachment charges and not call witnesses later this week. A Fox News poll released Sunday found that voters think the Senate already has enough evidence to render its verdict — 48 percent to 44 percent who say senators should subpoena witnesses. But by a margin of 6 percentage points, they think the evidence points to guilt and removal from office.

Two polls last week found that 51 percent of Americans want the Senate to convict and oust Trump, whose approval rating in the Fox News poll is 45 percent, 54 percent disapproval. By comparison, Fox News notes, "around the time former President Bill Clinton's impeachment trial began in January 1999, some 38 percent said the Senate should remove him from office, and 65 percent approved of the job he was doing as president."

Luckily for Trump, the party with a Senate majority is taking his side — 84 percent of Republicans told the Fox News pollsters that Trump shouldn't be convicted and removed, versus 81 percent of Democrats who said he should be; independents wanted Trump removed by a 19-point margin, 53 percent to 34 percent.

The poll was conducted Jan. 19-22 by Beacon Research (D) and Shaw & Co. (R), surveying 1,005 randomly selected registered votes over the phone. The poll's overall margin of sampling error is ±3 percentage points. Peter Weber

Justice Ruth Bader Ginsburg was hospitalized early Tuesday, after experiencing fever and chills, a Supreme Court spokeswoman said.

Ginsburg, 87, was evaluated at a hospital in Washington, D.C., on Monday night, before being admitted to Johns Hopkins Hospital in Baltimore. Spokeswoman Kathleen Arberg said Ginsburg "underwent an endoscopic procedure at Johns Hopkins this afternoon to clean out a bile duct stent that was placed last August. The justice is resting comfortably and will stay in the hospital for a few days to receive intravenous antibiotic treatment."

In May, Ginsburg received treatment at Johns Hopkins for a gallbladder condition. She has battled cancer four times, and last August, underwent radiation for a tumor on her pancreas. Catherine Garcia

The results from the first phase of Moderna's coronavirus vaccine trial are out, and the promising findings are in line with some early data from the study released in May.

The study, published Tuesday in The New England Journal of Medicine, found the experimental mRNA vaccine — which requires two doses a month apart — induced coronavirus immune responses in all 45 participants, just as scientists had hoped. There were some mild side effects, including fatigue, chills, and fevers, but The Associated Press notes those aren't uncommon with other vaccines, and there have been no major safety concerns.

Moderna will begin its final step at the end of July, a 30,000-person study to prove if the shots are strong enough to protect people from the virus. While the first phase does indicate the vaccine produces antibodies geared toward fighting off the virus, it's less clear if the levels of antibodies are enough to actually fend off infection. Read the full results of the study at The New England Journal of Medicine, as well as more context at The Associated Press. Tim O'Donnell

The creators of Glee are remembering Naya Rivera as a "joy to be around," and setting up a college fund for her young son, after her tragic death.

Glee creators Ryan Murphy, Brad Falchuk, and Ian Brennan released a tribute to Rivera on Tuesday after officials said they recovered her body at Lake Piru in California, where she went missing days earlier. The actress, who played Santana Lopez on Glee, was feared dead after her 4-year-old son was found alone in a boat she had rented. Ventura County Sheriff Bill Ayub said this week Rivera "mustered enough energy to get her son back onto the boat, but not enough to save herself," and an autopsy has since confirmed her cause of death as accidental drowning. She was 33.

"We are heartbroken over the loss of our friend Naya Rivera," Murphy, Falchuk, and Brennan said, per Variety. They described her as "one of the most talented, special stars we would ever have the pleasure of working with," someone who was "a joy to write for, a joy to direct and a joy to be around."

"She was warm and caring and fiercely protective of the rest of the cast," they go on to say. "She was tough and demanding. She was fun. She was kind. She was generous. ... Naya was more than just an actor on our show — she was our friend."

The statement ends with Murphy, Falchuk, and Brennan saying that their "hearts go out to her family" and that they are "in the process of creating a college fund for the beautiful son Naya loved most of all."

Among Rivera's former Glee colleagues who previously paid tribute this week were Jane Lynch, who remembered "what a force" she was, and Chris Colfer, who wrote, "Naya was truly one of a kind, and she always will be." Brendan Morrow

President Trump continued to stir controversy about the Confederate battle Tuesday during an interview with CBS News' Catherine Herridge.

Herridge asked Trump if he still believes, as he said in 2015, that the flag should be removed from public spaces and placed in museums. The president didn't explicitly answer the question, but he said the only thing he really cares about his "freedom of speech," indicating that he thinks people should be allowed to leave it up.

When Herridge reminded him the flag is a "painful reminder" for many people because the Confederacy rebelled against the United States to preserve slavery, Trump said he knows people "that like the Confederate flag" who are not "thinking about slavery" before once again turning the conversation back to the First Amendment.

Florida is now leading much of the world in new coronavirus cases, and it's showing no signs of slowing down.

Florida reported 9,194 new coronavirus cases in the past day on Tuesday afternoon, bring its total case count to 291,629. A total of 132 new deaths were reported, bringing that count to 4,409, per the Miami Herald.

Miami-Dade County led the new case count at 2,090, leading one infectious disease expert to deem Miami the new "epicenter of the pandemic," CNN reports. "What we were seeing in Wuhan six months ago, five months ago — now we are there," said Lilian Abbo, of the Jackson Health System, during a Monday news conference held by the Miami-Dade County mayor.

The county has seen coronavirus hospitalizations grow by 68 percent and the number of ICU beds used go up by 69 percent in the past two weeks. The number of ventilators in use has also more than doubled during that time. Kathryn Krawczyk

Immigration and Customs Enforcement has announced a "return to the status quo" on international student visas.

Following several schools' decisions to go fully remote to stem COVID-19 spread, ICE announced foreign students could not access essential F and M visas they'd need to study in the U.S. But facing opposition from more than 50 colleges and universities, the Trump administration rescinded that rule change, a federal judge in Boston announced Tuesday.

ICE's initial decision came after Harvard University and other schools announced all their classes would be fully online in the fall, though most schools said they'd house students who could not learn effectively in their homes. That included students in countries wracked by civil unrest.

Harvard and the Massachusetts Institute of Technology specifically cited those students in suing ICE for its decision, and said it "would bar hundreds of thousands of international students at American universities from the United States." Dozens of universities joined the suit, which went to court Tuesday. That's where a judge announced ICE would "return to the status quo" and effectively drop its rule change. Kathryn Krawczyk
