A release last week of texts showed that Christopher Steele, the former British spy whose memos regarding the Trump campaign’s possible ties to Russia are referred to as the Steele dossier, reached out to Sen. Mark Warner, the ranking Democratic member of the Senate Intelligence Committee, through a Russian-linked Washington, D.C., lobbyist named Adam Waldman. Among Waldman’s clients is Oleg Deripaska, a Russian aluminum magnate with close ties to Russian President Vladimir Putin. In a text dated March 16, 2017, Waldman texted Warner, “Chris Steele asked me to call you.”
