Mr Manafort worked as Mr Trump’s unpaid campaign chairman from March until August last year
US President Donald Trump’s former campaign chief has agreed to testify at an investigation into alleged links between the Trump team and Russia.
The chairman of the House intelligence committee, Devin Nunes, told reporters that Paul Manafort had voluntarily offered to speak to the panel.
Mr Nunes also contradicted Mr Trump’s claim that Barack Obama had wiretapped him before the US elections.
“There was no wiretapping at Trump Tower, that didn’t happen,” he said.
However, Mr Nunes said he was concerned that the names of members of Mr Trump’s transition team were “unmasked” during the surveillance of foreign individuals.
Earlier this week, AP news agency reported that Mr Manafort had worked for a Russian billionaire to assist Russian President Vladimir Putin.
Mr Manafort has insisted that he never worked for Russian interests.
He had worked as Mr Trump’s unpaid campaign chairman from March until August last year.
He resigned after AP revealed that he had co-ordinated a secret Washington lobbying operation on behalf of Ukraine’s ruling pro-Russian political party until 2014.
