United States presidential hopeful Elizabeth Warren has criticised Amazon Founder and CEO Jeff Bezos and former New York City Mayor Michael Bloomberg after reports surfaced that Bezos called the billionaire businessman to launch a 2020 presidential bid.

The New York Times reported that Bloomberg is preparing to file for the Alabama primary, whose deadline for doing so is Friday.

Don't worry too much about Mike Bloomberg - if history is any guide, if billionaires do nothing other than invest their wealth in the stock market, it's likely that their wealth will continue to grow.

And, according to a report from Recode's Jason Del Ray, Amazon CEO and world's richest person Jeff Bezos called Bloomberg earlier this year to gauge his fellow billionaire's interest in a presidential run.

Warren, who has championed her "Ultra-Millionaire Tax", took a shot at the billionaire following the report, encouraging him to fill out her calculator "for the billionaires".

Recode noted that Bezos has largely avoided electoral politics, and it is not clear whether he would actively support Bloomberg's candidacy.

Bezos is not the only billionaire who has expressed interest in a Bloomberg campaign.

If the singular issue of Medicare for All becomes increasingly linked with electability - the factor that remains many Democrats' top priority in the primary - it could spell trouble for Warren, who has already struggled with questions about whether she can beat President Donald Trump.

According to reports, Bloomberg, 77, is reportedly preparing to enter the Democratic race for the 2020 USA presidential election.

Another socialist Democratic candidate Bernie Sanders also reacted upon learning about Bloomberg 's recent move.
