Troubles continue to mount for U.S. Olympic swimmer Ryan Lochte, as four businesses announced Monday they are ending their sponsorship of the swimmer, as controversy over his claims of being a robbery victim in Rio De Janeiro continues.

Lochte, 32, claimed that he was robbed at gunpoint while he was in Rio for the Olympic Games. Those claims were later cast into doubt by Brazilian authorities, and Lochte’s teammates were detained by authorities in Brazil for some time, as a result.

Lochte subsequently issued an apology for his actions, on his verified Instagram account on August 19.

On Monday, Speedo issued the following statement on their sponsorship deal with Lochte, on its verified Twitter page.

Also on Monday, NBC News reported that clothing retailer Ralph Lauren and aesthetics company Syneron Candela have also dropped its sponsorship deal with Lochte.

In addition, Ralph Lauren also scrubbed all references of Lochte on its website.

On August 18, U.S. Olympic Committee CEO Scott Blackmun issued a statement, saying that they will “further review the matter, and any potential consequences for the athletes”, when they return to the U.S.
