Alabama Senator Jeff Sessions praised GOP frontrunner Donald Trump’s responses tohis GOP candidate questionnaire.

Sessions noted that to date Trump is the only candidate who has “answered to my satisfaction.”

On February 5th, Sessions, the intellectual thought leader of the conservative nation-state movement, issued a questionnaire to all candidates seeking the Party’s nomination. The Sessions test consisted of five straightforward questions addressing immigration, trade, and crime in the United States. In his response, Trump wrote, “After my inauguration, for the first time in decades, Americans will wake up in a country where their immigration laws are enforced.”

On Monday’s program of the Mark Levin Show, Sessions said:

The American people need to be alert. This is a very, very critical election. I think if they care about immigration issues and trade issues, they need to be sure about where their candidates stand. And I’ve asked them questions about trade and immigration and one question on crime. And Trump has answered to my satisfaction, but the others haven’t yet. So I think these candidates need to be specific about where they stand before Americans start giving them their vote.

“I’m a fan of Trump,” Sessions said. “He’s been clear on immigration, he’s been clear on trade, and he’s talking directly to the American people.”

Sessions said that he was similarly impressed with Trump’s picks for the Supreme Court. During Saturday night’s GOP debate, Trump was the only candidate to list his potential picks: Bill Pryor and Diane Sykes.

Sessions, who sits on the Senate Judiciary Committee, said “Trump really hit a home run with me when he mentioned [Pryor].”

“Sykes and Pryor are conservative federal judges,” Business Insider reports. Because Pryor is adamantly pro-life, “Senate Democrats tried to block Pryor’s nomination to the 11th Circuit court, saying that he had described Roe v. Wade as ‘the worst abomination in the history of constitutional law.'”

In recent days, Trump has been hitting Cruz for his prior support of John Roberts. In 2005, Cruz penned an op-ed in favor of Roberts’ confirmation, declaring: “John Roberts should be a quick confirm” for the Senate.
