He said that the president has helped Nigerians to wage a war against corruption.
The president's spokesperson said this while speaking during an interview on Gatefield Television on Monday, December 18, 2017.
While he failed to disclose if the president will seek reelection in 2019, Shehu noted that the president's track record in his first term speaks well for him.
He said, "He (Buhari) more than deserves a second term on account of the fact that the president has started something of a revolution in this country, because it will take a revolution to transform this country from a nation that did not even condemn corruption on the rhetorical level; that had embraced corruption from top to bottom. That's what the president is trying to change. To rid this country of corruption."
Shehu continued to laud the president's achievement in office especially in terms of security and agriculture, saying it has improved since before the president was sworn in.
He said, "If Buhari hadn't been here, Boko Haram would have been in Aso Rock by now; they would have taken over Abuja. You would not have been here talking to me, because they were everywhere.
"Boko Haram had reached Ibadan and Lagos. People look at this country and say nothing has been achieved. Can you build anything without peace in this country.
"This is a country that spent US$5 million every day importing rice; we're not doing that anymore. What more do you want us to say?
"We have created nearly half a million jobs for graduates through N-Power and all of these schemes. The president identified key issues and he was right."

While meeting with the Nigerian community in Abidjan, Cote d'Ivoire last month, the president explained that he was accompanied to the meeting by two state governors because it will "be another vote for me in the future."
Also, while speaking during a two-day visit to Kano State a week later, the president said he's confident of winning reelection particularly due to the crowd turnout.
"I am overwhelmed by the sea of people I see, and by what I see today, if elections are contested I will no doubt win it," he said.
