WASHINGTON (AP) -- President Donald Trump on Thursday signed a resolution condemning white supremacists and hate groups, hours after reviving his assertion that there were "bad dudes" among the people who assembled to oppose a white nationalist protest in Charlottesville, Virginia, last month.

"You know, you have some pretty bad dudes on the other side also," the president told reporters aboard Air Force once, sparking another round of criticism that the president has failed to adequately condemn hate speech.

The resolution, passed by Congress earlier this week, condemns "the violence and domestic terrorist attack that took place" in Charlottesville as well as white supremacists, neo-Nazis and other hate groups.

It also urges the president and his administration to "speak out against hate groups that espouse racism, extremism, xenophobia, anti-Semitism and white supremacy," and calls on the Justice Department and other federal agencies to "use all resources available" to address the growing prevalence of those groups.

"As Americans, we condemn the recent violence in Charlottesville and oppose hatred, bigotry, and racism in all forms," Trump said in a statement announcing the signing. He called on Americans to move forward "as one people" and "to rediscover the bonds of love and loyalty that bring us together as Americans."

Trump's earlier comments on Charlottesville came one day after he met in private with Sen. Tim Scott of South Carolina, the Senate's lone black Republican, at the White House. The two discussed the president's past remarks blaming "many sides" for the violence and death around a Confederate statue.

Recounting his conversation with Scott, Trump told reporters aboard Air Force One on Thursday: "I think especially in light of the advent of antifa, if you look at what's going on there, you know, you have some pretty bad dudes on the other side also. And essentially that's what I said."

"Antifa" is short for "anti-fascist," an umbrella description for far-left-leaning militant groups.

Trump added that more and more people are starting to agree with him.

"A lot of people are saying — in fact a lot of people have actually written, 'Gee Trump might have a point,'" Trump said. "I said, 'You got some very bad people on the other side also,' which is true."

Trump last month said there were "very fine people" among the nationalists and neo-Nazis protesting the possible removal of a Confederate statue in Charlottesville.

Scott said he told the president that there was no comparison.

"We had three or four centuries of rape, murder and death brought at the hands of the (Ku Klux Klan) and those who believe in a superior race," he told reporters at the Capitol. "I wanted to make sure we were clear on the delineation between who's on which side in the history of the nation."

Scott bluntly criticized Trump for assigning blame in a way that put white supremacist protesters on equal footing with counterdemonstrators who turned out for the Aug. 12 protests, sparked by Charlottesville officials' decision to remove a statue of Confederate Gen. Robert E. Lee.

That remark, Scott said, compromised Trump's moral authority as president.

On Wednesday, Trump told Scott that he just meant to convey "that there was an antagonist on the other side" — to which Scott replied, "The real picture has nothing to do with who is on the other side."

Scott continued: "I shared my thoughts of the last three centuries of challenges from white supremacists, white nationalists, KKK, neo-Nazis, so there is no way to find an equilibrium when you have three centuries of history."

The president said that he got the point, Scott said. Asked if the president can regain his moral authority, Scott responded, "That will take time."

White House spokeswoman Sarah Huckabee Sanders said Trump and Scott had an "in-depth" discussion about the Charlottesville comments, "but the focus was primarily on solutions moving forward."

"That was what both people came to the meeting wanting to discuss," Sanders said during a White House briefing. "What we can do to bring people together, not talk about divisions within the country."

Scott said Trump also brought up Seattle Seahawks defensive end Michael Bennett, who has accused Las Vegas police of using racially motivated excessive force against him.
