President Donald Trump vowed in his inaugural address Friday that every US decision would be guided by a vision that puts "only America first."

"From this day forward, a new vision will govern our land. From this day forward, it's going to be only America first," he said.

"Together we will make America strong again. We will make America wealthy again. We will make America proud again. We will make America safe again. And, yes, together, we will make America great again," Trump said as he concluded his address.
