ivanka trump and don jr. more on that investigation in a moment. first let s get to cnn national security correspondent kylie atwood at the state department. secretary blinken just spoke after meeting with ukraine s foreign minister. what came out of this meeting? reporter: pretty significant news from the secretary of state this morning, saying russia has about 100,000 troops on ukraine s border that we know. he went further and said russia could double that number on relatively short order. that is hugely significant. it s not just about the number of troops that russia has, but it s about the plans and capacity that they have for bolstering those troop levels to a higher number so they could then potentially invade ukraine. the other thing the secretary was asked about in this press conference with his ukrainian counterpart was what the u.s. would consider doing in terms of more military sis sentence to ukraine. he wasn t specific about what that assistance would look like.
