The New York Stock Exchange reopened at 3:10 p.m. ET Wednesday after floor trading in all symbols was halted for about 3 hours due to an apparent technical issue, CNBC reported. "We’re experiencing a technical issue that we’re working to resolve as quickly as possible. We're doing our utmost to produce a swift resolution & will be providing further updates as soon as we can," the NYSE tweeted Wednesday. They added that the issue is an "internal technical issue and is not the result of a cyber breach." White House Press Secretary Josh Earnest added that "There is no indication that there are malicious actors involved." Trading stopped around 11:30 a.m. ET. The Nasdaq reported no technical issues and said it continues to trade NYSE-listed stocks. Three U.S. officials told NBC News that there’s no indication that the computer problems at United Airlines and the New York Stock Exchange are related. A Treasury department spokesman said its officials are "closely monitoring the situation along with regulatory partners."
