Trump Realized He'd Messed Up With Putin When Even Newt Gingrich Criticized Him: Report

President Donald Trump reportedly recognized his mistake in siding with Russian President Vladimir Putin after some his top advisers, as well as former Speaker of the House Newt Gingrich, chastised his comments against the U.S. intelligence community.

Trump was unnerved by Gingrich's response to the president's suggestion that he believed Putin's denials of election meddling over the conclusion reached by U.S. intelligence agencies last year, according to The Washington Post, citing one unnamed source familiar with the White House's damage control following the press conference in Helsinki.

"President Trump must clarify his statements in Helsinki on our intelligence system and Putin. It is the most serious mistake of his presidency and must be corrected—-immediately," Gingrich tweeted Monday afternoon.

Gingrich has often praised and defended Trump from the media and establishment Republicans, potentially making such pointed criticism alarming to the president.

Trump also rolled back his statements Tuesday following the advice of White House Chief of Staff John Kelly, national security adviser John Bolton, Secretary of State Mike Pompeo and Vice President Mike Pence, The Post reported. Kelly even urged Republican lawmakers to speak out against Trump's comments.

The president's siding with Putin included his oft-repeated criticism of the FBI, Justice Department and Democrat Hillary Clinton. Speaking alongside the Russian leader, he again challenged the special counsel's investigation of Russia's meddling even after new charges were brought against 12 Russian military officers just days before the summit with Putin.

After Trump claimed Tuesday that he meant to say "wouldn't" as opposed to "would" in reference to whether or not he believed Russia interfered in the 2016 election, Gingrich took to Twitter to say Trump "did the right thing" by "clarifying" his comments.

Still, Trump's initial statement while standing beside Putin caused widespread condemnation from both sides of the political aisle. Current Speaker of the House Paul Ryan said Trump had to recognize that Russia was not an ally of the U.S., while Senator John McCain of Arizona said Trump had "abased himself" before a "tyrant" like Putin.

Despite his roll back, Trump's tweets both before and after attempting to clarify his statements call into question whether he actually does side with the U.S. intelligence community.

"The meeting between President Putin and myself was a great success, except in the Fake News Media!" Trump wrote Tuesday night, just hours following his clarification.

And on Tuesday morning Trump praised Senator Rand Paul of Texas, one of the few lawmakers to defend the president, when he tweeted and quoted Paul: " Thank you @RandPaul. 'The President has gone through a year and a half of totally partisan investigations - what's he supposed to think?'"

Trump also claimed Wednesday morning that "many people at the higher ends of intelligence loved" his press conference with Putin, while others wanted to see a "boxing match" between the two leaders.
