The New York Times reports:
The White House has determined that it will most likely have to allow the whistle-blower who filed an explosive complaint about President Trump to meet with congressional investigators, two people briefed on the matter said Tuesday. The meeting could give Democrats a stream of evidence as they consider whether to impeach the president.
Such a meeting would allow the whistle-blower to share at least some details of the complaint he filed — which relates to Mr. Trump’s efforts to get the Ukrainian government to investigate former Vice President Joseph R. Biden Jr. and his son — even if the actual document is not handed over to Congress.
The administration had originally barred the whistle-blower’s complaint from being shared with Congress, arguing that it did not meet the legal definitions of a matter under the purview of office of the director of national intelligence.
