Former presidential hopeful Jeb Bush criticized President Donald Trump's frequent tweeting and lack of focus on passing his agenda in an interview with CNBC at the eMerge Americas conference on Monday in Miami.

Bush, who served as governor of Florida, has been critical of Trump, dubbing him the "chaos candidate" during the presidential campaign. Despite heavy spending, Bush's own presidential run fell far short of expectations in a campaign cycle that rode a wave of populism.

Bush weighed in on a number of political issues, including former FBI Director James Comey's testimony with the Senate Intelligence Committee last week. Bush reaffirmed comments he previously made about how he does not think Comey's testimony indicated Trump committed obstruction of justice. He did say he thought that the president's alleged actions were inappropriate and hurt the country, however.

"Look, I didn't support Donald Trump. I didn't vote for him, but he's our president," Bush said. "I want him to succeed. I wanted Barack Obama to succeed, and anything that undermines the presidency weakens our ability to solve problems."

Bush has not been shy about his thoughts on Trump. Last week at Boston College, Bush urged Trump to focus on his job, according to the Boston Herald. In Las Vegas last month, Bush told the audience that the chaos of the Trump campaign has continued into his presidency, CNN reported. He urged Trump to stop tweeting and start governing.
