In his speech on July 4th – the day meant for unity and celebration – US President Donald Trump vowed to “safeguard our values” from enemies within labelling them as leftists, looters and agitators.

President Donald Trump has vowed to defeat the "radical left" in an Independence Day speech at the White House, condemning recent efforts to remove or rethink monuments to historical figures as attempts to destroy the US.

Trump's Fourth of July remarks doubled down on a Friday night speech at Mount Rushmore in South Dakota where he accused "angry mobs" of trying to erase history and used the speech to paint himself as a bulwark against left-wing extremism.

Millions of Americans have been demonstrating against police brutality and racial inequality since the May killing of George Floyd, a 46-year-old Black man who died after a white Minneapolis police officer knelt on his neck for nearly nine minutes.

'Their goal is demolition'

In addition to achieving police reforms in some cities, some protesters have removed Confederate statues and other symbols of America's legacy of slavery.

"There have always been those who seek to lie about the past in order to gain power in the present, those that are lying about our history, those who want us to be ashamed of who we are," Trump said on Saturday. "Their goal is demolition."

Anti-Trump protests

Protesters called for racial equality just steps from where Trump spoke in Washington, DC, marching down blocked-off streets around the White House, Black Lives Matter Plaza and the Lincoln Memorial.

Roar of the Deplorables, a bikers group, said via social media that they planned to gather in Washington on Saturday to stand in protest against what they call "the anti-Trump regime" and to celebrate the nation's birthday.

Freedom Fighters DC, a new activist group that seeks to rally an ethnically diverse generation of supporters behind liberty for all people, especially the Black population of Washington, is one of the anti-racism groups ignoring the mayor's heed to refrain from gathering.

"Black folks are not free from the chains of oppression, so we don't get to truly celebrate Independence Day," said Kerrigan Williams, 22, one of the founders of the group, which will host a march and an arts demonstration on Saturday afternoon.

"We're marching today to showcase that Black folks are still fighting for the simple liberties that the constitution is said to provide."

Biden targets Trump

Joe Biden, Trump's Democratic rival in the November election, wrote a Fourth of July op-ed piece that struck a contrasting note with the Republican president and accused him of finding everyday "new ways to tarnish and dismantle our democracy."

In a separate letter to donors, Biden said: "We have a chance now to give the marginalised, the demonised, the isolated, the oppressed, a full share of the American dream."

'China must be held accountable'

While criticism mounted over his handling of the pandemic, Trump said China must be "held accountable" for failing to contain the disease.

Trump claimed without evidence that 99 percent of cases in the United States were "totally harmless." In fact, many US states marked a record number of new Covid-19 cases. In Texas alone, 7,890 patients were hospitalised after 238 new admissions over the past 24 hours.

Trump, in his Saturday speech, also said the United States would have a vaccine or therapeutic solution to the virus "long before" the end of 2020.

On Thursday, a top US health official said he was optimistic the Trump administration’s vaccine-acceleration program “Operation Warp Speed” will generate a safe and effective vaccine for Covid-19 by year-end.
