When he was a US presidential candidate, Trump tweeted his approval of Hopkins in 2015, calling her a "respected columnist." Trump thanked her for defending him in an article which said that his views on Muslims reflected the views of millions of Americans.
In her article, Hopkins defended Trump's policy of a temporary ban on Muslim immigrants.
Hopkins wrote: "Trump wants to call a temporary halt to Muslim immigration until America figures out what is going on.
"Adversaries may be quick to jump on Trump and make him the problem.
"But look around. You are too busy gazing at the fluff in your navel to see the gangrene in your foot."
She praised Trump for "providing leadership" on terrorism unlike former president Barack Obama, whose approach made her want to "wrap a suicide vest around my head and text BOOM to my brain."
She also attacked multiculturalism in the UK and blamed it for Islamic terrorist attacks there and in Europe.
