U.S. Representative Steve Scalise has hit out at newcomer Alexandria Ocasio-Cortez's supporters claiming they are 'radical' after they mocked the mass shooting that he survived.

Scalise (R-La) and Ocasio-Cortez (D-NY) got into a heated Twitter exchange on Saturday as they debated her proposed hefty tax rates for the wealthy.

After some back-and-forth between the pair, Scalise tweeted screenshots of some responses from Ocasio-Cortez's supporters in which they said 'snipe his a**' and 'kick his cane'.

He argued that her supporters were 'radical'.

'Happy to continue this debate on the Floor of the People's House, but it's clearly not productive to engage here with some of your radical followers #StayClassy,' he tweeted.

The comments from Ocasio-Cortez's supporters were in reference to Scalise being seriously injured in 2017 when a gunman opened fire on a congressional Republican baseball practice.

The 53-year-old used a cane to help him walk during his recovery.

It was sparked by their earlier Twitter feud in which Scalise lashed out about Ocasio-Cortez's plans for a 70 percent tax on rich Americans to fund the Green New Deal program.

'Republicans: Let Americans keep more of their own hard-earned money Democrats: Take away 70% of your income and give it to leftist fantasy programs,' Scalise tweeted.

Ocasio-Cortez hit back: 'You're the GOP Minority Whip. How do you not know how marginal tax rates work? Oh that's right, almost forgot: GOP works for the corporate CEOs showering themselves in multi-million dollar bonuses; not the actual working people.'

Scalise appeared to end the debate when he posted the screenshots from Ocasio-Cortez's supporters.
