Trump unleashed his criticism on one of Wisconsin's favorite sons just before leaving Washington to visit the state, which he wants to win again in 2020.
"I could not stand on a campaign stage with the president when people shouted, 'Lock her up!' - and I'm not alone in that", the Arizonan said by phone Friday.
Trump also tweeted that Ryan failed to secure funding to build a southern border wall while Republicans controlled both chambers of Congress. "Never knew how to go after the Dems like they go after us".
"I told myself I gotta have a relationship with this guy to help him get his mind right", Ryan was quoted.
President Donald Trump hit back at former House Speaker Paul Ryan in a late-night Twitter thread, following reports of Ryan's comments in a scathing new book from POLITICO reporter Tim Alberta. One such Republican was Ryan, who reportedly told Alberta that he wanted to "scold" Trump "all the time" because Trump "didn't know anything about government". In the book, Ryan admits that his decision not to run for reelection was an "escape hatch" out of government and away from the Trump administration.
President Trump with House Speaker Paul D. Ryan (R-Wis.) after the passage of the tax bill on the South Lawn at the White House in Washington on December 20, 2017. And, truth be told, in his career in public office, Paul Ryan did at least as much damage to the country as the president* has.
'So Paul Ryan was not a talent.
He said: 'Speaker Paul Ryan is a truly good man, and while he will not be seeking re-election, he will leave a legacy of achievement that nobody can question'.
The president revived the attacks on Friday, accusing Ryan of being inept at fundraising, not being aggressive towards Democrats while Nancy Pelosi has handed out subpoenas "like cookies", and losing control of the House.
In a series of tweets on Thursday evening, Trump blasted the former Republican lawmaker from Wisconsin for "poor leadership and bad timing" during his House tenure. He was unable to raise money, he lost control of the house. This on-again-off-again duo has found their way back in the spotlight when President Trump nailed Rayan in the comments of a forthcoming book. When he announced his retirement in 2018, he said he doubted any political run was in his future.
Ultimately, Ryan came on board in the waning days of the election, saying his was a binary choice between Trump and Hillary Clinton, who he said would be a continuation of Democratic power in Washington.
