A second whistleblower has come forward with information about Donald Trump’s dealings with Ukraine as the US president faces an impeachment probe and an escalating political crisis.
Mark Zaid, an attorney specialising in national security issues, told US news channel ABC that the second whistleblower had first-hand knowledge of the allegations set out against Mr Trump and his officials in an original complaint that is at the centre of the impeachment probe.
On Twitter, Mr Zaid added that the second person had made “a protected disclosure under law”, and “cannot be retaliated against”. Mr Trump has called for the identity of the first whistleblower to be revealed.
