Caitlyn Jenner has said she asked son-in-law Kanye West if she can be his vice-president now he is running for office.

West announced he was running for president on July 4 and filed the official paperwork on Wednesday.

In the wake of the news TMZ approached Jenner and asked her what her reaction has been to the announcement. She replied: “Oh, I texted him and said, ‘Can I be your VP?’

“What a combination."

Jenner, stepdad to West’s wife Kim Kardashian, was married to Kris Jenner until 2015.

West polled at just two per cent last week which sparked rumours he may be dropping out of the race with his adviser Steve Kramer saying ‘he’s out’.

But the rapper is pursuing the political venture. West has missed the deadline to be included on the ballot in most states but he will appear in Oklahoma.

He has seen public support from his wife, entrepreneur Elon Musk and rapper 2 Chainz.
