Celebrity doctor Peter Attia has stepped down from his role as a CBS News contributor after exchanges with Jeffrey Epstein were among documents published by the US Department of Justice.

Attia appears to have exchanged a number of emails with the convicted sex offender, including a crass comment about women's bodies.

Attia's spokesman said in a statement his role at CBS News "was newly established and had not yet meaningfully begun" and he would be step back to avoid becoming "a distraction from the important work being done at CBS".

The anti-ageing influencer has repeatedly apologised for the messages but stressed he had no involvement in Epstein's criminality.

Appearing in the files does not imply any wrongdoing.
