Trump has repeatedly dismissed the document as false and in recent days has questioned on Twitter whether Democrats or the FBI had helped fund it. The dossier, which circulated in Washington last year and was turned over to the FBI for its review, contends that Russia was engaged in a longstanding effort to aid Trump and had amassed compromising information about him. Yet the FBI has worked to corroborate the document, and in a sign of its ongoing relevance to investigators, special counsel Robert Mueller’s team - which is probing potential coordination between Russia and the Trump campaign - weeks ago questioned the former British spy, Christopher Steele, who helped compile the claims in the dossier. The revelation is likely to fuel complaints by Trump that the dossier, which the president has derided as “phony stuff,” is a politically motivated collection of salacious claims. WASHINGTON - Hillary Clinton’s presidential campaign and the Democratic National Committee helped fund political research into President Donald Trump that ultimately produced a dossier of allegations about his ties to Russia, a person familiar with the matter said Tuesday night.
