Jeb Bush, who challenged Donald Trump for the Republican presidential nomination, has advised the president to be more careful about what he says.
The former Florida Governor made the remarks in an interview with WFOR on March 26, CNN reports.
"He should stop saying things that aren't true, that are distractions from the task at hand," said Bush, according to CNN. "He's got a lot of work to do, and some of these things -- the wiretapping, all of this stuff -- is a complete distraction that makes it harder to accomplish the things I know he wants to do."
Bush's message to Trump was not entirely negative.
"He hasn't shifted to being president in the way that people are used to, and I think that's the problem," he added. "The strength is he's acted in a good way and lifted people's spirits in terms of economic growth and job creation, but he's a distraction in and of himself."
Bush argued that Trump still had to get used to the difference between being on the campaign trail and working in the White House, particularly when it comes to his use of Twitter.
"I hope he learns it's one thing to do it as a candidate, where you're garnering a huge following on Twitter and people go to massive rallies where people clearly love him," added Bush. "Another thing is when you're the president; your words have consequences that go way beyond that."
Trump has repeatedly defended his use of Twitter, including since entering the White House.
Speaking to Fox on Feb. 28 ahead of his first address to Congress, Trump stated that Twitter allows him "to go around dishonest media."
"Most of the people that want me to stop it are the enemies, I'll be honest with you," Trump added, according to Fortune. "If I felt the media were honest, all of it, or most of it, I wouldn't do it. But it is a modern day form of communication."
Bush is not the only former rival of Trump to recently comment on the president.
At a speech in San Francisco on March 28, Hillary Clinton, Trump's Democratic opponent in the Nov. 8 election, criticized the administration's "bad policies that will hurt people and take our country in the wrong direction," according to Mercury News.
Clinton took aim at the failed attempt by Trump and the Republicans to reform Obamacare, also known as the Affordable Care Act.
"When Congress and the administration tried to jam through a bill that would have kicked 24 million people off their health insurance, defunded Planned Parenthood, jeopardized access to affordable birth control, deprived people with disabilities and the elderly and nursing homes of essential care, they were met with a wave of resistance," Clinton added. "And when this disastrous bill failed, it was a victory for all Americans."
