Sean Spicer said that Mr Trump’s explosive allegations over the weekend still stood, and that the president would now wait for investigations to run their course.
Asked whether it was not a waste of time and money for congressional and senatorial committees to investigate Mr Trump’s baseless allegations, Mr Spicer replied that it was “not about new proof”.
The White House press secretary devoted much of his press conference to detailing Monday night’s proposal for a new Republican healthcare plan.
He also sought to clarify Mr Trump’s accusation that Mr Obama had made “another terrible decision” to release prisoners from Guantanamo Bay – and wrongly stating official figures to justify his attack.
In a day which was designed to be all about the Republicans’ much-vaunted healthcare plans, Mr Trump started the day by claiming that 122 “vicious” Guantanamo inmates had returned to the battlefield, “released by the Obama administration”.
