Timothy Weah, the son of Liberia’s President George Weah, scored for the US in their World Cup opener against Wales that ended in a draw.
Tim Weah finished smartly after a surging run and pass by Christian Pulisic.
Gareth Bale rode to Wales’ rescue with a late penalty.
President Weah is in Qatar for nine days to watch his American-born son play in the World Cup.
His trip has sparked controversy back home after the country’s finance minister said the president was “entitled” to $2,000 (£1,700) daily allowance during his stay in Qatar.
Critics say awarding Mr Weah such a huge amount a day goes against his promise to reduce public spending in favour of his “pro-poor agenda”.
