Trump family critics did not respond kindly when Ivanka Trump, a White House aide and Donald Trump's daughter, showed off her fan mail on social media.

“Overjoyed by these beautiful letters. Reading them is one of the highlights of my week,” Ms Trump posted on Twitter, along with a photo of her reading the notes covered in, ‘thank you’s’, yellow smiley faces, hearts, and messy handwriting.

One letter depicted a face with green dollar signs.

“Dollar Signs for Eyeballs=The Trumping Down of America. First Family used to teach children to value respect & compassion over pure greed,” one Twitter user responded.

Another wrote, “Whatever staffer made these fake letters to Ivanka Trump, I loved this little touch - was it a commentary on being blinded by greed?

Several people on social media questioned why Ms Trump was being thanked.

“Why would anybody, especially children, send thank you letters to Ivanka Trump?” a Twitter user wrote.

Others suggested that the President had sent the letters.
