Child protester's vitriolic message for Donald Trump

A young protester has shared his hate of Donald Trump during one of many rallies that broke out across the US during the inauguration of the 45th President of the United States.

As Trump was sworn into office this morning, thousands of people of all ages took to the streets in anger during a mass coordinated rally.

One young boy who claimed responsibility for starting a fire outside the National Press Club in Washington DC told a Fox News reporter exactly what he thought about his new leader.

"My name’s Connor and I actually kinda started this fire. I felt like it and screw our president," the boy yelled before re-joining the rest of the protesters.

Police across the US made more than 100 arrests overnight as crowds massed to show their disdain at Trump's election.
