"We stand by our words that the government of Ukraine didn't help any candidate in [the] election." the embassy stated. "Ukraine is proud of bipartisan support in the United States."
Earlier on Tuesday, US President Donald Trump reiterated a claim that Ukraine tried to sabotage his campaign and promote that of his opponent Hillary Clinton.
In a Twitter post, Trump also criticized US Attorney General Jeff Sessions for not investigating the alleged link between Kiev and the Clinton campaign.
The website cited Chalupa as saying she occasionally shared her findings with the DNC and Clinton campaign officials and discussed Manafort with Ukraine’s Ambassador to the United States Valeriy Chaly.
Chalupa has since called the Politico story nonsense and disputed Trump's claims that the DNC told her to get information from the Ukrainian embassy. The DNC and former Clinton campaign officials have denied working with the Ukrainian government to get information about Manafort or Trump.
