President Donald Trump's predictable response erupted Wednesday evening when he demanded The New York Times reveal the anonymous writer behind the infamous op-ed.

"Does the so-called 'Senior Administration Official' really exist, or is it just the Failing New York Times with another phony source?" he tweeted. "If the GUTLESS anonymous person does indeed exist, the Times must, for National Security purposes, turn him/her over to government at once!"

Trump has already indicated he thinks it might be treasonous.

It wouldn't be the first time a reporter was jailed in the United States after the government demanded a source.

In 2005, New York Times reporter Judith Miller was jailed after refusing to divulge a source who disclosed the name of CIA operative Valerie Plame. She was in jail for three months before she finally cut a deal with prosecutors. spent three months in jail before cutting a deal with prosecutors. Vice President Dick Cheney's chief of staff Scooter Libby was the one behind it.

No reporter has been jailed for refusing to divulge a source in the last 10 years.
