Donald Trump Jr. praised law enforcement officials for their response to the hoax white powder attack that targeted him — but caused his wife to get rushed to a Manhattan hospital on Monday.

“A special thanks today to the great men & women of the @NYPDnews @FDNY @SecretService @NewYorkFBI and the Joint Terrorism Task Force for their decisive action and incredible words of support to my wife and family,” Donald Jr. tweeted.

“Their professionalism under pressure made a rough day manageable.”

Earlier in the day, Trump Jr.’s wife, Vanessa, was rushed to a Manhattan hospital when she opened an envelope that had a mysterious white powder inside — which turned out to be cornstarch.

“Thank you so much for all the help today in NYC!” Vanessa Trump tweeted Monday night.

“I appreciate all the quick response to make sure that I was safe ! Thank you @FDNY @SecretService @NYPDnews @NYPDCT @NewYorkFBI”

The envelope was addressed to Donald Trump Jr.

“Thankful that Vanessa & my children are safe and unharmed after the incredibly scary situation that occurred this morning,” he wrote in another tweet.

“Truly disgusting that certain individuals choose to express their opposing views with such disturbing behavior.”
