Senate passes bill to fix PPP loan program, sends to Trump for signature
Senate Majority Leader Mitch McConnell, R-Ky., asked for a unanimous consent vote Wednesday evening and received no objection hours after Sen. Ron Johnson, R-Wisc., objected to its passage because he wanted assurances of changes to be made at a later time to the program.
It now awaits President Donald Trump's signature.
The bill, called the Paycheck Protection Flexibility Act, eases restrictions on the popular program and comes after the program was scrutinized for providing aid to unintended recipients, such as large publicly-traded companies and many businesses around the country complained they either could not tap into loans or did not receive adequate funds to keep their business afloat and employees on the payroll.

The findings, published Wednesday in the New England Journal of Medicine, are the first from a major clinical trial looking at whether the medication might be useful as a prophylactic.
The study included 821 people who had been in close contact with a confirmed COVID-19 patient, putting them at an elevated risk of developing the illness themselves.

The country’s largest annual technology trade show, CES, is still on track to be held in Las Vegas in January, organizers said in a post on the event's website.
“We all face new considerations around attending conferences, conducting business and traveling to meetings,” said the Consumer Technology Association, the group behind the event. “Just as your companies are innovating to overcome the challenges this pandemic presents, we are adapting to the evolving situation.”
The hands-on event typically draws around 175,000 people and features innovative products and devices for attendees to try out.
The group said it will expand its selection of livestreamed CES content and roll out new cleaning and social distancing practices. It will expand aisles in many exhibit areas and add more space between seats in conference programs.
For 2021, attendees will be encouraged to wear masks and avoid shaking hands.
The event will have cashless purchase systems to limit touch points and provide enhanced on-site access to health services and medical aid.

Trump administration bans Chinese carriers from flying into the U.S.
The Department of Transportation plans to ban Chinese carriers from flying passengers to the U.S, after Beijing declined to increase the number of flights it allows to the United States. The news was first reported by Reuters.
“This action responds to the failure of the Government of the People’s Republic of China to permit U.S. carriers to exercise their bilateral rights to conduct passenger air service to China," the DOT said in a statement on Wednesday.
While Delta and United are operating cargo flights to China, both airlines are still waiting for approval for daily passenger flights. Four Chinese carriers currently operate scheduled passenger flights between the U.S. and China.
“We support and appreciate the U.S. government’s actions to enforce our rights and ensure fairness,” a Delta spokeswoman told NBC News.
The action comes just days after Trump warned China that businesses with close connections to Beijing would come under greater scrutiny in the United States. The two countries are in the midst of a trade war and a disagreement over China’s decision to exert greater control over Hong Kong.

University of Southern California to resume in-person classes in August
In a letter posted on the University of Southern California's website Tuesday, USC president Carol L. Folt said administrators are "planning for an in-person fall semester for students beginning on August 17, 2020, a week earlier than originally scheduled."
"All classes, including final exams, will end by Thanksgiving. By ending the semester before Thanksgiving, we are aiming to minimize the spread of the virus, particularly as the flu season commences. To support this schedule, we will not have a fall break in 2020," Folt said in the letter.
Folt added that the plans "remain contingent on several factors, including the continued spread of COVID-19, and the health orders from state and local authorities."
