Ivanka Trump and Wendi Deng Murdoch went sightseeing in Dubrovnik, Croatia, according to an Instagram post uploaded to the account of the GOP presidential nominee's daughter.

Donald Trump's daughter has previously shared a photo of Murdoch, calling her a "remarkable woman" and "one of those friends that inspires you to work hard, be better and laugh louder."

Their friendship comes to light at a time when her father's ties to the Kremlin have drawn a few raised eyebrows. Earlier this year, US Weekly reported that the ex-wife of media mogul Rupert Murdoch was dating Vladimir Putin. In July, Wendi Murdoch denied the rumor to Vogue, saying she has never met the Russian president.

On Monday, The New York Times reported that Putin's main ally in Ukraine earmarked $12.7 million in secret cash payments to Paul Manafort, now Trump's campaign chairman, from 2007 to 2012. In a statement Monday, Manafort called the report "unfounded, silly and nonsensical." He added that he had never taken an "off-the-books cash payment" nor worked for the governments of Ukraine or Russia. system.

Last month, the Republican presidential nominee said Trump hopes Russia finds emails deleted by Hillary Clinton from her time as secretary of state.
