After Vanessa Trump was released, Donald Jr. decided to take to Twitter [VIDEO]on February 12 to give an update on his wife, while lashing out at those who have taken their criticism of the administration to the next level.

"Thankful that Vanessa & my children are safe and unharmed after the incredibly scary situation that occurred this morning," Donald Trump Jr. wrote. "Truly disgusting that certain individuals choose to express their opposing views with such disturbing behavior," he added.

In a follow-up tweet, the younger Trump gave thoughts to those who assisted his wife and family following the scare. "A special thanks today to the great men & women of the NYPD, FDNY, Secret Service, New York FBI and the Joint Terrorism Task Force for their decisive action and incredible words of support to my wife and family," Donald Jr. wrote, while concluding, "Their professionalism under pressure made a rough day manageable."

After Donald Jr.

sent out his pair of tweets, some critics still weren't sympathetic [VIDEO]. "Disgusting people attract disgusting behavior," the offical Socialist Party Twitter account wrote.

"Maybe you should reflect on the tone and tenor of your texts and public statements so as to not encourage those crazy people. You can make valid points without being a complete and total D-ick," one tweet read. "Where's your proof that it was the opposition? Think before you act Donnie," an additional tweet noted.

"You should be taking care of your family instead of tweeting about it for attention," a follow-up tweet stated. "Please start a go fund me, so we can all chip in with medical fees.
