The Trump administration granted two authorizations to U.S. companies to share sensitive nuclear power information with Saudi Arabia shortly after the killing of journalist Jamal Khashoggi in October, a U.S. senator who saw the approvals said on Tuesday.

The timing of the approvals is likely to heap pressure on the administration of President Donald Trump from lawmakers who have become increasingly critical of U.S. support for Saudi Arabia since Khashoggi was killed in the Saudi consulate in Istanbul in October.

Khashoggi, a native of Saudi Arabia, left in 2017 to became a resident of the United States where he published columns in the Washington Post critical of the kingdom's leadership.
