It looks like Jeff Sessions committed perjury

At attorney general appointee Jeff Sessions January confirmation hearing, Senator Al Franken asked him, "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, who was sworn in, said, "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."

It appears the Sessions committed perjury.

From New Republic:

But George Papadopoulos's guilty plea indicates that there were attempts in the Trump campaign to arrange a meeting with Putin, and that Sessions was aware of them. As CNN reports this morning, "The chairman of Trump's national security team, then Alabama Senator and now Attorney General Jeff Sessions, shut down the idea of a Putin meeting at the March 31, 2016, gathering, according to the source. His reaction was confirmed with another source who had discussed Sessions's role."
