Trump casts blame on both sides for deadly violence in Virginia

NEW YORK, Aug 15 (Reuters) - U.S. President Donald Trump unabashedly insisted on Tuesday that both left- and right-wing extremists resorted to violence during a weekend rally by white nationalists in Virginia, and that some present were peacefully protesting plans to remove a Confederate monument when the upheaval began.

Trump, taking questions from reporters in the lobby of Trump Tower in New York, reverted to his initial comments blaming "many sides" for Saturday's violence in Charlottesville, a day after bowing to pressure to explicitly condemn the Ku Klux Klan, neo-Nazi and white supremacist groups.

"They came at each other with clubs ... it was a horrible thing to watch," Trump said during what was supposed to be an announcement about his administration's infrastructure policy. He also said left-wing protesters "came violently attacking the other group."

Trump has faced a storm of criticism from Democrats and members of his own Republican Party over his response to the deadly violence, which erupted after white nationalists converged in Charlottesville for a "Unite the Right" rally in protest of plans to remove a statue of Robert E. Lee, commander of the pro-slavery Confederate army during the U.S. Civil War.

Many of the rally participants were seen carrying firearms, sticks and shields. Some also wore helmets. Counter-protesters likewise came equipped with sticks, helmets and shields.

The two sides clashed in scattered street brawls before a car plowed into the rally opponents, killing one woman and injuring 19 others. A 20-year-old Ohio man, James Fields, said to have harbored Nazi sympathies, was charged with murder.

Two state police officers also were killed that day in the fiery crash of the helicopter they were flying in as part of crowd-control operations.

Addressing the melee for the first time on Saturday, Trump denounced hatred and violence "on many sides." The comment drew sharp criticism across the political spectrum for not explicitly condemning the white nationalists whose presence in the Southern college town was widely seen as having provoked the unrest.

Critics said Trump's remarks then belied his reluctance to alienate extreme right-wing organizations, whose followers constitute a devoted segment of his political base despite his disavowal of them.

Yielding two days later to a mounting political furor over his initial response, Trump delivered a follow-up message expressly referring to the "KKK, neo-Nazis and white supremacists and other hate groups" as "repugnant to everything we hold dear as Americans."
