According to Sky News:

Joe Biden has signed with Los Angeles talent agency Creative Artists Agency (CAA), home to stars such as Brad Pitt, Ariana Grande and more.

A spokesperson told FNN:

Former President Biden is not expected to join the after-dinner speaking circuit as is popular with many former politicians.

Instead a number of businesses have expressed interest in having Biden represent them, including Care Home providers and manufacturers of:

• Incontinence pants
• Stairlifts
• Shampoos

We think former President Biden has a lucrative future ahead of him promoting age-related goods and services and will prove a big draw, especially in post-war Ukraine.
