Former US President Donald Trump has launched his third bid for the White House, declaring: "America's comeback starts right now."

At his Florida estate, he said: "We have to save our country."

Mr Trump's announcement comes as some fellow Republicans blame him for the party's lacklustre performance in last week's midterm elections.

Newshour's James Menendez has been speaking to Jason Miller, a senior advisor for Mr Trump. How much of a liability is Mr Trump's announcement to the Republican Party?
