Turning Point's Charlie Kirk says that white supremacy in America isn't a thing because Asian Americans earn a lot of money

Racist tweets by Donald Trump - in which he told four Democratic congresswomen to “go back and help fix the totally broken and crime infested places from which they came” - have dominated Washington politics this week.

The attack on young progressives Alexandria Ocasio-Cortez, Ilhan Omar, Ayanna Pressley and Rashida Tlaib saw outraged Democrats leap to their defence and denounce the president as Republicans slunk off into the shadows, working overtime to avoid reporters pressing microphones into their faces with an invitation to call out their leader.

Trump himself would not back down or apologise and just kept on hammering out more and more obnoxious tweets, accusing "The Squad" (as the congresswomen are known) of being "anti-Israel, pro Al Qaeda" and "hating our country".

When he was asked about whether he was concerned that his views aligned with those of white nationalists, Trump answered:

It doesn't concern me because many people agree with me.

As the row rumbled on, the four women held a press conference warning America not to "take the bait" and succumb to the president's dog whistle racism before the House of Representatives voted in favour of a resolution condemning his words.

As with the administration's detention of asylum seekers at the US-Mexico border, this latest Trump scandal has inspired a heated debate about the treatment of immigrants in American society (despite all four of his targets being American citizens and only Omar born outside of the US).

Fox News has particularly struggled with the situation, largely sticking to attacking the quartet for their "socialism" as a means of sidestepping difficult questions about race.

The network's guests this week have included: Newt Gingrich, who said The Squad constitute a "fascist movement"; Louisiana senator John Kennedy, who called them "the four horsewomen of the apocalypse" and "whack jobs"; and the president's son Eric Trump, who said they were the "most hate-filled group I've ever seen".

Charlie Kirk, the founder and leader of conservative nonprofit Turning Point USA, had an interesting take of his own, appearing on The Story with Martha MacCallum to argue the president's tweets were not racist because white supremacy does not exist in America.

Asked by the host about the "mantle of shame" associated with anti-immigrant sentiment, Kirk answered:

If this was really true, why is it that Asian Americans are actually the wealthiest and highest incomes [sic] of any group in America?

That would actually go against the idea that the entire country is built on white supremacy still and, again, the US constitution was not written in Korean, it wasn't written in Chinese...

It shows that any individual, any person that comes here with hard work and entrepreneurial attitude can succeed.

So that's all right then. White supremacy is not a problem everyone! There are several wealthy Asian Americans out there so you can all go home.

Charlottesville, Richard Spencer, the Proud Boys - forget about it.
