The White House said Wednesday that there is no indication that "malicious actors" were involved in the technical problems that halted the New York Stock Exchange at about 11:30 a.m.

Presidential press secretary Josh Earnest said top White House aides have briefed the president on the situation and would continue to do so throughout the day.

"At this point there is no indication that malicious actors are involved in this technical issue," he said. Earnest added that White House officials "have been in close touch with the Department of Homeland Security and the Security [sic] and Exchange Commission, as well as the Treasury Department."

Earnest also noted with a "high degree of confidence" that the computer problems that grounded United Airlines flights Wednesday was not related to the technical glitch at the NYSE.

Officials at the stock exchange are working "feverishly" to update these government entities on the nature of the technical problems the NYSE experienced Wednesday, he said.

Earnest also cited the information sharing between the NYSE, a private entity, with the federal government about the technical problem as an "important element" of the Obama administration's strategy to safeguard "our system from cyber threats."

Trading was halted for more than two hours on the NYSE floor because of an apparent technical issue. The NYSE tweeted that there was no sign of a cyberattack. It did not immediately provide a timetable for when floor trading would resume.

Earnest said he didn't know whether the federal government would launch an investigation into the technical glitch, and said it's too early to tell what kind of impact the glitch would have on the market.

"At this point, it's too early to offer an assessment," he said.
