Monday's biggest developments:
Here's how the news unfolded Monday. All times Eastern.
Colorado joined the list of states that are closing food and entertainment businesses as U.S. public life grinds to a halt.
Health officials in Colorado announced they are closing bars, restaurants, gyms, theaters, and casinos effective at 8 a.m. Tuesday for 30 days.
"We understand the gravity of this public health order, and the disruption it will cause,” Jill Hunsaker Ryan, executive director of the Colorado Department of Public Health and Environment, said in a statement Monday. "But we are weighing this disruption against the need to save lives. Based on the experience of other countries, the state of Washington, and modeling data, the sooner we begin social distancing measures on a large enough scale, the more quickly we can slow transmission of the virus, which translates into less people requiring hospitalization at the same time and more lives saved."
Major cities including Washington, D.C., and Houston rolled out similar restrictions earlier Monday. The governors of New York, New Jersey and Connecticut also announced that they would abide by the same rules for closures.
The three states agreed to close gyms, movie theaters and casinos as of 8 p.m. Monday, with all restaurants and bars restricted to takeout and delivery only.
McDonald's officials said they plan to close the dining rooms in all company-owned U.S. locations at the close of business on Monday, and they have asked local franchise owners to do the same.
"To align with increasing regulations throughout the country, effective at the close of business today, McDonald’s USA company-owned restaurants will close seating areas, including the use of self-service beverage bars and kiosks, and shift our focus to serving customers through Drive-Thru, walk-in take-out and McDelivery,'' the company said in a statement Monday night.
The fast-food giant will also close all of its play places after Monday.
McDonald’s, which owns about 5 percent of its nearly 14,000 U.S. restaurants, said franchise owners are "strongly encouraged to adopt similar operations procedures."
"Franchisees are strongly encouraged to adopt similar operations procedures while keeping the needs of their people and communities at the center of their decisions," the statement said. "This guidance is supported by franchisee leadership and is expected to be adopted by the majority of franchisees."
Starbucks, Chick-fil-A and Taco Bell are among the chains that are also reducing or eliminating on-site dining during the COVID-19 outbreak.
The attorney general is directing states to prioritize the prosecution of scammers, fraudsters and cybercriminals looking to exploit the COVID-19 crisis.
"The pandemic is dangerous enough without wrongdoers seeking to profit from public panic and this sort of conduct cannot be tolerated," U.S. Attorney General William Barr wrote in a memo sent to U.S. attorneys offices around the country Monday evening. "Every U.S. attorney's office is thus hereby directed to prioritize the detection, investigation, and prosecution of all criminal conduct related to the current pandemic."
The memo also asks U.S. attorneys to work with the chief judges in their districts "to ensure that every appropriate precaution is taken to protect the health of those who practice in or are called before our courts."
"It is vital that we work together to safeguard our justice system and thus the safety and security of our nation," Barr said.

The Department of Health and Human Services experienced suspicious cyberactivity Sunday night related to its coronavirus response, administration sources confirmed to ABC News Monday.
The suspicious activity HHS was not a hack but it may have been a distributed denial of service -- or DDOS -- attack, according to multiple sources.
Major airlines could be bankrupt by the end of the year without action, industry group warnsThe distinction is important because there was no apparent breach of the HHS system, which could interfere with critical functions of the lead agency responding to the coronavirus contagion. The DDOS effort apparently had automated users -- called bots -- trying to overwhelm the public-facing HHS system in order to slow it down or even paralyze it.
Officials believe any coordinated effort -- if there was one -- was not particularly successful and are satisfied that the system was not significantly affected.
HHS spokesperson Caitlin Oakley said in a statement: "HHS has an IT infrastructure with risk-based security controls continuously monitored in order to detect and address cybersecurity threats and vulnerabilities. On Sunday, we became aware of a significant increase in activity on HHS cyber infrastructure and are fully operational as we actively investigate the matter."
"Early on while preparing and responding to COVID-19, HHS put extra protections in place," Oakley added.

Cuomo said the U.S. has "been behind this disease from day one. We saw the disease developing in China back in November. We weren't ready for it, and we've been playing catchup ever since."
"The wave is going to break on the hospital system," he warned. "We don't have the capacity to build more hospitals quickly. The only way would be if the Army Corps of Engineers came in, worked with the states to retrofit existing buildings."
Cuomo announced Monday that all schools in New York state will close beginning Wednesday.
All non-essential and non-emergency travel in New Jersey is “strongly discouraged” from 8 p.m to 5 a.m., Gov. Phil Murphy added Monday.

Mitchell spoke to "GMA" anchor Robin Roberts via video Monday as he self isolates.
"I don't have any symptoms -- I could walk down the street. If it wasn't public knowledge that I was sick, you wouldn't know it," Mitchell said. "I think that's the scariest part about this virus -- you may seem fine, be fine, and you never know who you may be talking to, who they're going home to."
China is relaxing travel restrictions in the hardest-hit virus province of Hubei and sending thousands of workers back to jobs at factories desperate to get production going again.

Nine Network entertainment editor Richard Wilkins, 65, said he was tested because he met Wilson at the Sydney Opera House on March 7 and again at Nine's Sydney studio on March 9. The result came back positive on Sunday.
"I'm surprisingly very well," Wilkins told Nine by Facetime from his Sydney home, where he has self-isolated since Wilson's diagnosis.
You could've knocked me over with a feather last night when I got that call. It took me a couple of minutes to reel from the news that they gave me. But I feel fine. I feel 100%," Wilkins added. "We're assuming this is from Rita. It may not be. They've all said it could be anyone, anywhere, any time, such is the prevalence of this thing."
Wilson and her husband Tom Hanks have been isolated in an Australian hospital since they were both diagnosed with COVID-19 on March 12.
