Jaime Harrison: Donald Trump 'killing' Republican Party

US President Donald Trump has been the best recruiter for the Democratic Party, the associate chair of the Democratic National Committee, Jaime Harrison, has said.

He told BBC Hardtalk’s Stephen Sackur that President Trump's actions were “killing” the Republican Party in the long term and “splintering” it like no-one else.
