“The news that the ultra-liberal, elitist, out-of-touch New York Times Editorial Board endorsed an ultra-liberal, elitist, out-of-touch candidate in Hillary Clinton has to be some of the least surprising news ever," senior communications adviser Jason Miller said in a statement.

Miller called the Time's editorial board the "embodiment of the rigged system Donald Trump is running against."

"Mr. Trump far prefers the endorsement of hard-working Americans across this country than an editorial board that only seems to care about the plaudits they receive at cocktail parties and dinners in the power corridors of this country," Miller said.

The New York Times on Saturday announced its endorsement of the Democratic nominee.

In the editorial, the Times touted Clinton's record, while criticizing the GOP nominee for his lack of transparency.

"Hillary Clinton — has a record of service and a raft of pragmatic ideas, and the other, Donald Trump, discloses nothing concrete about himself or his plans while promising the moon and offering the stars on layaway," the editorial said.

The Times plans to publish a subsequent editorial explaining why Trump is the "worst nominee put forward by a major party in modern American history."
