Small-business loan program ran out of money within minutes, some banks say

Much of the $350 billion in the Small Business Administration's emergency coronavirus relief fund was effectively spoken for within the first minutes of launch, according to senior banking executives.

"We didn't even get through the first five minutes of applications," a JPMorgan Chase senior executive said, noting that the bank received over 60,000 applicants for the Paycheck Protection Program within those first five minutes.

A senior Bank of America executive said the bank was getting over 10,000 applications per hour, and Wells Fargo said over 170,000 "expressions of interest" were filed with the bank within just the first two days.

For the past two weeks, small-business owners have been checking their emails and calling their bankers and the SBA to check on the status of their application, not knowing that the first phase of the program was over before it barely began.

More than $1.8 trillion may be ultimately needed to meet the needs of small-business owners, by one estimate.

Navy reports 669 cases from USS Roosevelt

With a vast majority of USS Roosevelt crew members tested, the U.S. Navy reported Saturday that it has now has 669 coronavirus cases among the nearly 5,000 people who worked aboard the aircraft carrier.

The number of infected patients represents an increase of 84 compared to 585 on Monday. Ninety-four percent of those assigned to the ship have been tested so far, the Navy said in a statement Saturday.

Eight sailors are being treated for COVID-19 symptoms at U.S. Naval Hospital Guam, where the vessel is docked; one was in intensive care, the Navy said. One sailor, Aviation Ordnanceman Chief Petty Officer Charles Robert Thacker Jr., 41, of Fort Smith, Arkansas, died Monday from virus-related illness, the Navy said.

The ship's outbreak following a March 5 port of call in Da Nang, Vietnam, sparked controversy when pleas for help from its captain, Brett Crozier, were leaked to a newspaper. Crozier was removed from the ship's command by acting Navy Secretary Thomas Modly, who subsequently resigned amid a backlash to his criticism of the captain.
