The undated communications, which are allegedly from the iPhone of Manafort’s daughter, include a text that appears to come from a Ukrainian parliamentarian named Serhiy Leshchenko, seeking to reach her father, in which he claims to have politically damaging information about both Manafort and Trump.

Attached to the text is a note to Paul Manafort referring to “bulletproof” evidence related to Manafort’s financial arrangement with Ukraine’s former president, the pro-Russian strongman Viktor Yanukovych, as well as an alleged 2012 meeting between Trump and a close Yanukovych associate named Serhiy Tulub.

“Considering all the facts and evidence that are in my possession, and before possible decision whether to pass this to [the National Anti-Corruption Bureau of Ukraine] or FBI I would like to get your opinion on this and maybe your way to work things out that will persuade me to do otherwise,” reads the note. It is signed “Sergii” — an alternative transliteration of Leshchenko’s given name — and it urges Manafort to respond to an email address that reporters have used to reach Leshchenko.
