The highest-ranking Democrat on the US Senate intelligence committee said it was "extremely disturbing" if President Donald Trump was contemplating a pardon for aides that could be implicated in a probe on Russian meddling in last year's presidential election.
Senator Mark Warner was referring to a Washington Post article late Thursday saying that Trump was consulting with advisers "about his power to pardon aides, family members and even himself" in connection to the probe led by special counsel and former FBI director Robert Mueller.
" The possibility that the President is considering pardons at this early stage in these ongoing investigations is extremely disturbing," said Warner, the senior senator from Virginia and vice-chair of the Select Committee on Intelligence.
"Pardoning any individuals who may have been involved would be crossing a fundamental line."
The White House has yet to comment on the Post report.
However in an interview with the New York Times on Wednesday, Trump warned Mueller that some of his family finances should be off-limits to the ex-FBI director's wide-ranging investigation.
