The United States has never decided to hold back security assistance to Ukraine. This is written on the official website of the White House with reference to the press secretary of the US President Jen Psaki.
"The idea that we have held back security assistance to Ukraine is nonsense. Just last week - in the run-up to the US-Russia Summit - we provided a $150-million package of security assistance, including lethal assistance. We have now provided the entire amount appropriated by Congress through the Ukraine security assistance initiative," Psaki said in a White House statement.
The response from the White House came hours after Politico reported the Biden administration temporarily halted a military aid package to Ukraine that would have included lethal weapons to address aggressive Russian troop advancements along the Ukraine border earlier this year. The report cited four sources familiar with internal discussions on the matter who claimed the package would be worth up to $100 million.
Psaki said the administration had "now provided the entire amount appropriated by Congress through the Ukraine security assistance initiative."
The press secretary also restated Biden's comments two days before the summit in Geneva, in which he said the administration would maintain putting Ukraine "in the position to be able to continue to resist Russian physical aggression."
