Speaker of the House Nancy Pelosi, D-Calif., said Saturday that there has been a shift in public opinion among Americans in support of impeachment due to emerging details about President Donald Trump's call with Ukrainian President Volodymyr Zelensky.

"In the public, the tide has completely changed; it could change now, who knows? But right now after seeing the complaint and the IG (Inspector General) report and the cavalier attitude the administration had toward it, the American people are coming to a completely different decision," Pelosi said at the Texas Tribune Festival in Austin, Texas.

Pelosi on Tuesday announced an impeachment inquiry after a whistleblower complaint that President Trump spoke with Zelensky about ordering investigations into Democratic presidential candidate Joe Biden and his son Hunter. Pelosi had described Trump's actions as a "betrayal of his oath of office" and added that "no one is above the law." She said she wants to move "expeditiously" on the impeachment inquiry.

Pelosi's role in pushing for impeachment has been contentious. She had previously expressed reluctance to launch an impeachment inquiry into Trump during and immediately after the Mueller Report, fearing that it would divide the country and that there wasn't strong enough evidence. She had led several House committees to investigate the president on issues such as his tax returns and possible Russian collusion.

Some tallies show that roughly 90% of the 235 House Democrats support the impeachment inquiry into Trump, along with one Republican and one independent.

Pelosi has also stated that Attorney General William Barr had "gone rogue" and alleged an attempted coverup of the whistleblower's report.

Trump has called the inquiry "a witch hunt" and "the greatest scam in the history of American politics." The Trump campaign has said it raised at least $13 million since Pelosi launched the impeachment inquiry.
