Berry, who won gold in the Peruvian capital, was not included on a list of 100 elite American athletes set to receive grants this year published by the USATF Foundation.

This is despite the 31-year-old ranking sixth in the World Athletics standings and second among American women.

Compatriot and fellow thrower DeAnna Price, ranked number one in the world, received a top-tier $20,000 (£16,000/€18,000) grant. 

Four other hammer throwers - one woman and three men - received $5,000 (£4,000/€4,400) grants. 

Those four athletes are ranked 11th, 10th, 11th and 32nd in the world, respectively.

"I told you the truth.. here is the proof.. the word hypocrisy wouldn’t even suffice to describe this," Berry tweeted in response to her omission.

"And I dare someone tell me I don’t qualify.

"You say you support the Black Lives Matter movement yet you DEFUND the very athlete who took an stand when it was not popular."

In an interview with Yahoo Sports, Berry said the omission was due to her protest, claiming she had her funding threatened by a USATF Foundation official after raising her fist on the podium in Lima.

Just days after winning her gold medal, Berry was moved down to the second tier of grantees, each of whom received $4,000 (£3,200/€3,600).

She had received a grant of $35,000 (£28,000/€31,200) in 2018 as one of 25 US track and field stars in the top tier. 

"I know for sure that I wasn't chosen because of my stance on the podium," said Berry.

"Because I was told that."

The USATF Foundation rejected Berry's claim in a statement and said that she had been offered a separate grant of $5,000, which Berry turned down.  

"In a perfect world, the Foundation would give all of our grantees more money but the demand exceeds the need at this point as we have over 250 applicants," it said. 

"Gwen’s allegation that her stance on the podium at the Pan Am Games adversely affected our grant-making decisions in 2020 is inaccurate."

Berry and fencer Race Imboden were sanctioned with a year's probation by the United States Olympic and Paralympic Committee (USOPC) after protesting on separate occasions at the Pan American Games. 

USOPC chief executive Sarah Hirshland was criticised by Berry, however, after publishing a letter addressing the widespread Black Lives Matter demonstrations across the world.

In the letter, Hirshland said that USOPC "stands with those who demand equality" before later apologising to Berry.

Berry demanded an apology from USOPC for her punishment after Lima 2019, and was then "able to express my grievances" in a telephone conversation with Hirshland and USATF officials.

The United States Olympic and Paralympic Committee Athletes' Advisory Council has since called on the International Olympic Committee to scrap Rule 50, which states: "No kind of demonstration or political, religious or racial propaganda is permitted in any Olympic sites, venues or other areas."
