The images were shown on Tuesday evening, in connection with Trump's arrival in the United Kingdom. Among other things, news headlines, pictures of Trump and Epstein side by side were shown, but also a picture of Epstein walking side by side with Prince Andrew of the United Kingdom.
Recently, the developments surrounding Donald Trump's connection to Epstein have intensified, among other things, because a letter that Trump is said to have sent to Epstein has been made public. Trump denies that it is he who wrote it. The President has also sued the newspaper The Wall Street Journal after publications about Trump and Epstein.
Prince Andrew of the United Kingdom has also had connections to Epstein, something that has shaken the British royal family.
