Last month Trump’s national security adviser, Michael Flynn, was forced to resign amid controversy over his discussions with Kislyak in late December.
On Thursday, it emerged that Kushner joined Flynn at a private meeting with the ambassador at Trump Tower in New York. Another campaign aide, Carter Page, did not deny meeting Kislyak during the Republican national convention. And the Wall Street Journal reported that Trump’s son, Donald Jr, was probably paid at least $50,000 for an appearance late last year at a French thinktank whose founder and wife have strong ties to Russia.
