Real estate mogul Donald Trump let loose on Twitter with a series of doomsday predictions following news that a pair of Americans who had contracted the Ebola virus would be brought to the U.S. for treatment.

Trump began his rant Thursday night and quickly ratcheted up the rhetoric, including condemning the two aid workers who contracted the virus while treating Ebola patients in Africa.

“People that go to far away places to help out are great,” Trump wrote in one tweet, “but must suffer the consequences!”

Here’s a small taste of Trump’s outrage, which also included retweets from others who praised his stance on the matter:

Ebola patient will be brought to the U.S. in a few days – now I know for sure that our leaders are incompetent. KEEP THEM OUT OF HERE! — Donald J. Trump (@realDonaldTrump) August 1, 2014

Stop the EBOLA patients from entering the U.S. Treat them, at the highest level, over there. THE UNITED STATES HAS ENOUGH PROBLEMS! — Donald J. Trump (@realDonaldTrump) August 1, 2014

The U.S. cannot allow EBOLA infected people back. People that go to far away places to help out are great-but must suffer the consequences! — Donald J. Trump (@realDonaldTrump) August 2, 2014
