Ivanka Trump said it was "beautiful" to see thousands of anti-fascist protestors denouncing racism and anti-Semitism in Boston and New York on Saturday as her father continued to make ambiguous comments that failed to specifically condemn far-right groups inciting hatred across the US.

Ms Trump, 35, ensured she couldn't be accused of making an equivalence between white supremacist groups and counter-demonstrators by tweeting: "It was beautiful to see thousands of people across the U.S.A come together today to peacefully denounce bigotry, racism & anti-semitism.

"We must continue to come together, united as Americans!"

Her remarks followed rallies at Boston Common park and Google's corporate campus in New York which saw thousands of activists shouting anti-Nazi chants and carrying signs that read "racism is not patriotism" and "white nationalism is terrorism".

Hours earlier Donald Trump had reacted to footage of the largely anti-fascist crowds in Boston by tweeting: "Looks like many anti-police agitators in Boston. Police are looking tough and smart! Thank you."

He later said: "I want to applaud the many protestors in Boston who are speaking out against bigotry and hate. Our country will soon come together as one!"

Critics will claim that the President's comments bear echoes to his reaction to the violence which left one dead and dozens injured at a white supremacist rally attended by neo-Nazi and Ku Klux Klan groups in Charlottesville, Virginia, earlier this month.

Mr Trump initially blamed “hatred, bigotry and violence on many sides” after far-right sympathiser James Alex Fields Jr allegedly rammed his car into counter-protestors, killing 32-year-old Heather Heyer and leaving several others seriously injured in the Virginian city.

Democrats and Republicans condemned the President for appearing to compare the racist groups with what he called the "alt-left" counter-protestors after the fatal attack.

Mr Trump eventually condemned racism specifically after his initial comments were described as "really, really good" on the website Daily Stormer, an American neo-Nazi and white supremacist site which considers itself to be part of the alt-right movement.

Anti-fascist activists gathered in Boston Common park to oppose a "Free Speech Rally" organised by The Boston Free Speech Coalition.

The group was founded by student John Medlar, 23, to voice opposition to violent protests launched against the University of California Berkeley's decision to invite controversial figures, including Ann Coulter and Milo Yiannopoulos, to speak on campus.

Both Ms Coulter and Mr Yiannopoulos's planned talks were cancelled after protestors damaged buildings on campus.

He spoke about "loyalty" and "healing wounds" left by decades of racism.

Mr Medlar insisted that the rally in Boston was not about Confederate monuments or white supremacy, but acknowledged that at least one white nationalist group had tried to attend.

Several participants dropped out after the violence in Charlottesville, and on the day the counter protestors greatly outnumbered those attending the free speech rally.

In New York around 100 anti-fascist activists gathered outside Google headquarters and chanted against Mr Trump, the KKK and neo-Nazis on Saturday.

They had planned to oppose a rally by right-wing groups in support of the Google engineer James Damore, who was fired after penning a controversial memo that blasted the company's efforts to increase the number of minorities and women in its ranks and leadership positions.
