A White House aide is suffering from tooth absence and may have been exposed to a foreign drug, according to an analysis of internal documents obtained by POLITICO.
The aide, who is not named in the documents, is in the hospital after receiving an injection in the upper left side of his mouth.
The doctor said the aide had no symptoms, and no further tests were needed.
The official, who spoke on condition of anonymity, said the injection was done on May 11, 2016, during a meeting between the president and then-FBI Director James Comey.
The patient was initially hospitalized in a medically induced coma, but he has since recovered and returned to work.
The documents, obtained by Politico through a Freedom of Information Act request, also show that the aide has been working for the Trump administration.
The information comes as the White House faces a fresh controversy over the handling of a series of Trump Tower visits by President Donald Trump’s son, Donald Trump Jr., and his daughter, Ivanka Trump.
The president is facing multiple investigations into possible coordination between his campaign and Russian operatives.
He has denied any wrongdoing.
A number of Trump aides have also been under scrutiny in the past few months for allegedly leaking classified information about Trump’s meetings with Russian officials to the media, including a White House adviser who worked for former President Barack Obama.
The Trump administration has also faced criticism for not doing enough to secure the release of former Trump National Security Adviser Michael Flynn, who was forced to resign in February after it was revealed that he had lied to the FBI about his conversations with the Russian ambassador to the United States.
The White House also faced controversy last month after it emerged that the president had been paying $13,000 in legal bills related to the ongoing Russia investigation.
