SEC Closes Insider-Trading Investigation into Ex-Sen. Richard Burr’s Stock Sales

“The SEC this week told Mr. Burr, a North Carolina Republican who retired from the Senate at the start of the year, that it closed the investigation and wouldn’t take enforcement action against him.” Regulators had earlier said that Mr. Burr had material nonpublic information about the Covid-19 pandemic in February 2020 when he sold virtually all of the stock he owned through a retirement account.
