The Justice Department is closing investigations into three U.S. senators for stocks trades made shortly before the coronavirus market turmoil, but is continuing a related investigation into Sen. Richard Burr, according to people familiar with the matter.

Prosecutors on Tuesday are alerting defense attorneys for Republicans Kelly Loeffler of Georgia and James Inhofe of Oklahoma as well as Democrat Dianne Feinstein of California, that they are closing investigations into their trading, the people said.
