Sessions, who was the first senator to endorse Trump’s campaign, suffered a huge falling out with the president over his decision to recuse himself from the federal probe into Russia’s involvement in the 2016 election. Trump has said naming Sessions as attorney general was the “biggest mistake” of his presidency, and he has called his leadership of the Justice Department “a total joke.”
Sessions resigned at Trump’s request a year ago.
In a statement posted to his campaign website, he offered effusive praise of the president despite their rift.
“As everyone knows, President Trump and I have had our ups and downs. But here’s the important part: the President is doing great work for America,” he said. “When President Trump took on Washington, only one Senator out of a hundred had the courage to stand with him: me. I was the first to support President Trump. I was his strongest advocate. I still am. We must make America great again.”
He is expected to make a formal announcement on Fox News’ Tucker Carlson Tonight later Thursday.
