Andrew and Tristan Tate were seen hugging UFC president and Trump ally Dana White in Las Vegas on Friday, three days after Florida opened a criminal investigation into the brothers.
The Tates recently travelled to the US from Romania, where they face charges of rape, trafficking minors, and money laundering.
They face separate charges of rape and human trafficking in the UK, along with another civil case in the US, and deny all charges.
A penny for the thoughts of Keir Starmer, who faces renewed calls to get the brothers extradited to the UK after it was revealed last week that Kyle Clifford watched several Andrew Tate videos ahead of raping and murdering his ex-girlfriend Louise Hunt, and murdering her sister and her mother, in Hertfordshire.
Prosecutors said Clifford was fuelled by Tate’s “violent misogyny”.
The judge excluded evidence about Clifford’s viewing habits, which he said was of “limited relevance”.
