One of presumptive Republican nominee Donald Trump’s 11 potential Supreme Court nominations, Justice Don Willett from the Texas Supreme Court, mocked the real estate mogul repeatedly on Twitter.

“Willett poked fun at Trump’s campaign slogan, at Trump University, at the billionaire’s attempts at evangelical outreach, at his ideological commitment to conservatism, and even at his spelling,” Vox reports. “Amusingly enough, Willett even wrote that his ‘mind reels’ when trying to think of whom ‘the Donald’ would name to the Supreme Court.”

On Wednesday, Trump revealed 11 judges whom he would consider if elected President of the United States to replace Justice Scalia, who passed away in February, on the Supreme Court.
