Ayade, who is also a presidential hopeful, met with Tinubu when the latter visited Cross River on Wednesday.
In his remarks, the former Lagos governor promised to improve the economy of Cross River if he is elected president.
“Mine is to respect you as you respect me. I appeal to you as your senior brother and the first to declare his intention, not to endorse me today, but when you get to Abuja, you can endorse me fully,” Tinubu said, according to a statement by his media office.
“We must have that unity of purpose. We must work together not only for the unity and economic development of Cross River, but also of the country. We owe that to the present and future generations.”
