US House Speaker Mike Johnson said on February 14 there was an unspecified “serious national security threat,” confirming an unusual cryptic statement issued earlier in the day by House Intelligence Committee chairman Mike Turner.Two sources familiar with the issue said Turner’s statement, which was circulated to all members of the House, was related to Russia and its operations in space, without providing further details on what was described as a highly classified matter.Johnson told reporters at the Capitol there was no need for public alarm.”Steady hands are at the wheel. We’re working on it and there’s no need for alarm,” he said.
