Rep. Alexandria Ocasio-Cortez told her followers there was "no sugarcoating" Sen. Bernie Sanders's performance against Joe Biden in the latest round of 2020 Democratic primaries.

"There's no sugarcoating it. Tonight is a tough night," the New York Democrat said Tuesday night on Instagram Live. "Tonight is a tough night electorally."

Biden topped Sanders in four of the six states that voted in the March 10 contests.

"If you win a race, you win a race," Ocasio-Cortez said about Biden's wins.

The congresswoman has been critical of the former vice president, saying in the past that the Democratic Party has "too big of a tent."

"In any other country, Joe Biden and I would not be in the same party, but in America, we are," she added at the time.

Ocasio-Cortez has said, however, that she would support Biden if he secures the party's nomination.

"I’ve said throughout this entire process that what is so important is that we ultimately unite behind who that Democratic nominee is," she told Late Night host Seth Meyers last week.

As of Wednesday morning, Biden leads Sanders in the delegate count by around 823 and 663 respectively. A total of 1,991 delegates are required to become the party's next standard-bearer.
