Mr Trump's campaign planned to announce his selection publicly today, but cancelled the event because of the attack in Nice.

Other candidates in the running were former House Speaker Newt Gingrich and New Jersey Governor Chris Christie.

Indiana Governor Pence, is strongly anti-abortion and signed a religious freedom bill, which some saw as anti-gay, into law.

Trump and Pence are divided on some key issues including Trump's call to ban Muslim from entering the US.

Calls to ban Muslims from entering the U.S. are offensive and unconstitutional.
