Ivanka Trump Socializes with Old Friend Wendi Deng, Putin Rumors IntensifyIvanka Trump met up with Wendi Deng Murdoch, but the two are old friends and the latter denies she's ever met Vladimir Putin, much less is dating the Russian president.
In a vacuum, the claim sounded quite scandalous. The often inaccurate site Occupy Democrats published a piece titled "Trump’s Daughter and Putin’s Girlfriend Just Went on Vacation Together," intimating the women's camaraderie was something that had just been uncovered.
