Donald Trump wants Americans to dump their iPhones and MacBooks.

The Republican frontrunner for President unleashed a series of tweets on Friday calling for the boycott after the company’s decision to fight a court order calling for it to hack an iPhone used by the San Bernardino shooter.

“I use both iPhone & Samsung,” he wrote to his more than 6 million followers. “If Apple aapl doesn’t give info to authorities on the terrorists I’ll only be using Samsung until they give info.”

He added in another tweet, “Hopefully others will follow suit. Our country needs & should demand security. It is time to get tough & be smart!”

In a third, he wrote, “Boycott all Apple products until such time as Apple gives cellphone info to authorities regarding radical Islamic terrorist couple from Cal”

The call to boycott Apple comes days after Trump, along with fellow candidate for President Marco Rubio, criticized the company for its decision.

“I agree 100 percent with the courts—in that case we should open it up. I think … we have to open up, and we have to use our heads,” Trump said in an interview on Fox News.

Meanwhile, one Twitter user made the point that despite his call for the boycott, his campaign had a merchandise table set-up with iPads to pay for merchandise.

The news comes as Apple has been named No. 1 in Fortune’s 2016 World’s Most Admired Companies franchise list.

Fortune has reached out to Apple for comment, and we will update this post once we hear back.
