Federal law prohibits foreign donations to federal campaigns, political action committees and inaugural funds.
In April raids of Mr. Cohen's home, office and hotel room, Federal Bureau of Investigation agents obtained a recorded conversation between Mr. Cohen and Stephanie Winston Wolkoff, a former adviser to Melania Trump, who worked on the inaugural events.
"We have just received a subpoena for documents", said the spokesman to ABC News. "While we are still reviewing the subpoena, it is our intention to cooperate with the inquiry", a spokesperson for the committee said in a statement.
Federal prosecutors in NY issued a subpoena Monday seeking documents from Donald Trump's inaugural committee, furthering a federal inquiry into a fund that has faced mounting scrutiny into how it raised and spent its money.
In December, the Journal reported that federal prosecutors were investigating whether the inaugural committee misspent some of the record $107 million it had raised from donors.
They also requested documents relating to donations "made by or on behalf of foreign nationals, including but not limited to any communications regarding or relating to the possibility of donations by foreign nationals".
Tom Barrack, the inaugural committee's chairman, also declined to comment.
The investigation partly arises out of materials seized in the federal probe of former Trump lawyer Michael Cohen's business dealings, according to people familiar with the matter. The Russia inquiry, which has ensnared several senior figures from his presidential campaign, appears close to the end. "The biggest thing the president did in his engagement with the inauguration was to come out here and raise his hand and take the oath of office". Cohen, who Trump has derided as a bumbling lawyer who did little work for him, has slowly emerged over the a year ago as a key source of legal peril for Trump, organisations he's linked to and his close associates.
