Kamala Harris has been criticised for giggling when asked if the US should take more Ukrainian refugees.

The vice president, who is on a three-day trip to Poland and Romania, laughed when asked the question at a press conference in Warsaw alongside Polish President Andrzej Duda.

She looked at Mr Duda as if he should respond first, then smirked: “A friend in need is a friend indeed.”

Victoria Spartz, a Ukrainian-born Republican representative, criticised Harris, saying it was “a very serious situation requiring action” and is “not a laughing matter”.

George Papadopoulos, Donald Trump’s former campaign aide, added: “Discussing refugees is no laughing matter. Why she laughs at this is deranged.”

Ms Harris has previously been criticised for laughing at odd moments during press conferences on serious issues.

Following the US’s withdrawal from Afghanistan last year, she giggled as she told reporters to “hold on” and “slow down” as they asked questions.

Ms Harris’ trip comes after a potential deal between Poland and the US to send fighter jets to Kyiv collapsed.

Poland has taken in almost 1.5 million refugees who have fled Ukrainian after Russia’s invasion.

Harrowing scenes have been recorded at train stations as Ukrainians desperately try to get to the border.
