Jan. 10, 2017: At the Judiciary Committee confirmation hearing, the topic of Russia came up when Sessions was questioned by Sen. Al Franken, D-Minn. Here is the relevant part of that exchange:
Franken: "If there is any evidence that anyone affiliated with the Trump campaign communicated with the Russian government in the course of this campaign, what will you do?"
Sessions: "Senator Franken, I'm not aware of any of those activities. I have been called a surrogate at a time or two in that campaign and I didn't have -- did not have communications with the Russians, and I'm unable to comment on it."
