Michael Bloomberg's latest presidential campaign ad features footage of several former presidents and the current occupant of the Oval Office, but it does not show the man paying for the ad. Bloomberg's new "Bring Presidential Back" spot compares some of President Trump's more vulgar moments to soaring speeches from John F. Kennedy, Lyndon Johnson, Ronald Reagan, George W. Bush, and Barack Obama.

To be fair, soaring rhetoric isn't really Trump's thing, and it isn't Bloomberg's strong suit, either. But Trump likes to pantomime being "presidential" as stiff and boring, and Bloomberg's ad reminds viewers that past presidents could thrill with their words while elevating the dignity of the office. In another ad released over the weekend, Bloomberg takes aim at what Trump believes to be his strongest card, the economy. Again, Bloomberg only makes a brief cameo at the end.

It's unusual for a presidential candidate, especially in a primary race, to make ads that don't feature the candidate — but there's very little that's conventional about Bloomberg's run. He has already spent $310.4 million on digital and TV advertising this year, more than the $115.3 million spent by all the other Democrats combined, Axios reports, and he also outspent all the other candidates combined in the last quarter, plus both the Republican National Committee and the Democratic National Committee.

"Bloomberg is betting that enough exposure — through a $300m+ ad campaign and a non-traditional run that looks past the early four states — will make him competitive in Super Tuesday, and make all Democrats stronger in the general election," Axios explains. "He's blowing through cash to create a parallel (or bigger) unofficial, uncoordinated party infrastructure in case the DNC can't help the eventual Democratic nominee enough in states that should be competitive with Trump."

One day after President Trump tweeted that the stock market is "starting to look very good to me," the markets just once again took a dive.

The Dow Jones Industrial Average fell 879 points on Tuesday after the Centers for Disease Control came out with a dire warning about the coronavirus, saying its community spread in the United States appeared inevitable and Americans should be ready for the potential of major disruptions in their lives, CNBC reports.

Additionally, the S&P 500 on Tuesday fell about 3 percent, and CNBC notes that "the last time the S&P 500 fell more than 3 percent two days in a row was in November of 2008 during the financial crisis," citing Bespoke Investment Group.

Dr. Nancy Messonnier of the CDC's National Center for Immunization and Respiratory Diseases said Tuesday that the coronavirus spreading in the U.S. is "not so much of a question of if" but rather "a question of when," and "we are asking the American public to prepare for the expectation that this might be bad," The New York Times reports.

This came after the Dow on Tuesday plunged 1,031 points in what NBC notes was its worst performance in two years. Brendan Morrow

White House officials aren't on the same page as top health officials.

President Trump's economic adviser Larry Kudlow on Tuesday told CNBC there was basically nothing to worry about when it comes to the coronavirus' effect on the U.S. "We have contained this. I won't say [it's] airtight, but it's pretty close to airtight," he said. He also reassured viewers that while the coronavirus may be a "human tragedy," it won't be an "economic tragedy," since there aren't any "supply disruptions" just yet.

Supply disruptions may be one thing, but the Centers for Disease Control and Prevention nearly simultaneously warned of incoming "disruption to everyday life," saying the spread of the coronavirus in the U.S. is "not so much of a question of if" but rather "a question of when."

As CNN's Phil Mattingly put it, Kudlow's comments are "more or less, the exact opposite of what lawmakers were told in a briefing from top [Trump administration] health officials this morning." FiveThirtyEight's Nate Silver seemingly agreed Kudlow's (and President Trump's) comments were misguided, tweeting it "seems very very very very risky for the Trump administration to claim coronavirus is contained in the U.S. if it later proves not to be contained."

Perhaps Kudlow realized he may have sounded a bit too optimistic, because shortly after his CNBC appearance he told reporters the possibility of further travel restrictions are "under discussion." He continued, "I'm going to wait on that. I don't want to get ahead of my skis or their skis. It's all under discussion."

Still, he insisted the U.S. is very prepared for anything the coronavirus may throw our way. "We're not going to get caught with our pants down," he predicted, per Bloomberg's Jennifer Jacobs. "The virus is not going to last forever." Harvard epidemiologists may have something to say about that. Summer Meza

The Centers for Disease Control is warning Americans to prepare for the possibility of a severe disruption of their lives as a result of a coronavirus outbreak in the United States.

Dr. Nancy Messonnier of the CDC's National Center for Immunization and Respiratory Diseases said Tuesday that the spread of the coronavirus in the U.S. is "not so much of a question of if" but rather "a question of when," The New York Times reports.

Messonnier also told Americans they should "prepare for the expectation that this might be bad," saying schools may need to use "internet-based teleschooling," business may need to use "video or telephone conferences and increase teleworking options," and communities might have to "modify, postpone, or cancel mass gatherings," CNBC reports.

"Now is the time for businesses, hospitals, communities, schools, and everyday people to begin preparing," she said. "I understand this whole situation may seem overwhelming and that disruption to everyday life may be severe. But these are things that people need to start thinking about now." Messonnier also explained that she has told her family they "ought to be preparing for significant disruption to our lives."

Health officials also briefed members of Congress about the coronavirus threat on Tuesday, after which Sen. Patty Murray (D-Wash.) said, per The Washington Post, that lawmakers were warned there's a "very strong chance of an extremely serious outbreak of the coronavirus here in the United States." More than 50 cases have been confirmed in the U.S. Meanwhile, President Trump has downplayed the threat, saying on Tuesday, "I think that whole situation will start working out." Brendan Morrow

Sen. Elizabeth Warren (D-Mass.) is on good terms with some Democratic exes.

While she can't claim to have raised thousands of dollars from ex-boyfriends, like Sen. Amy Klobuchar (D-Minn.) can, Warren has remained quite friendly with several ex-Democratic presidential candidates. In an interview with NBC News, Warren said she's texted nature photos with Washington Gov. Jay Inslee (D) shortly after he dropped out of the race, talked math with Andrew Yang, and kept in touch with former Housing Secretary Julián Castro, who has endorsed her run.

But she says Sens. Kamala Harris (D-Calif.) and Kirsten Gillibrand (D-N.Y.) have particular insight into what NBC News calls the "loneliness" of the campaign trail, something Warren described as like "living in a movie that is running at high speed with everything coming so quickly."

"Kamala and Kirsten, in particular, ask me am I getting rest? Am I eating? And am I having some fun out there?" said Warren of her fellow women candidates. "It's a very personal experience to run. Running for president can be thrilling but also very lonely," she said. "The candidate stands alone."

Warren even got back in good graces with former Rep. John Delaney (D-Md.) after taking him down a few pegs in one of the first debates. Delaney said her call to wish him well after he dropped out was "quite lengthy and quite in-depth" and showed "she's not entirely self-absorbed. She actually listens."

Former New York City Mayor Michael Bloomberg's partner has weighed in on his company's nondisclosure agreements, and her response isn't proving to be much less controversial than his.

Bloomberg's longtime partner Diana Taylor spoke to CBS This Morning on Tuesday after the former mayor during last week's Democratic debate defended his company's nondisclosure agreements and said no women have "accused me of doing anything, other than maybe they didn't like a joke I told." Bloomberg later said he'd release three women from their NDAs signed to "address complaints about comments they said I had made," saying they were signed over the "past 30-plus years."

Taylor defended Bloomberg on Tuesday, saying he wasn't "accused of doing anything or saying something nasty to a woman" but that "I grew up in that world" and "it was a bro culture."

CBS News reports that among the women released from NDAs with Bloomberg was a former sales rep who sued the former mayor and alleged that she told him she was pregnant and he responded, "kill it."

Asked what she would say to those bothered by the allegations against Bloomberg and his recent dismissive comments about the use of nondisclosure agreements, Taylor was similarly dismissive, saying, "It was 30 years ago. Get over it."

After Sen. Elizabeth Warren (D-Mass.) grilled Bloomberg on this issue during the Nevada Democratic debate, don't be surprised to see it come up again during tonight's South Carolina debate, which airs at 8:00 p.m. Eastern on CBS. Brendan Morrow

The coronavirus crisis continues, with more than 2,500 fatalities worldwide. But as NPR reports, the number of reported cases in children is surprisingly low. "We're seeing [about] 75,000 total cases at this point, but the literature is only reporting about 100 or so pediatric cases," Terri Lynn Stillwell, a pediatric infectious disease expert at Mott Children's Hospital at the University of Michigan, tells Morning Edition. One small study of infected infants in Wuhan, China, found that the virus presented as a "very mild illness," causing a fever and cough but no severe complications in the children. It's much more dangerous — and deadly — for elderly patients.

Researchers aren't sure why young children seem more resilient to the virus, but Sallie Permar, a professor of pediatrics and immunology at Duke University School of Medicine, told NPR it could come down to antibodies passed along from mothers. Jessica Hullinger
