We get it. Presidential campaigns are a blur. One day you're kissing babies in an Iowa cornfield, the next you're working the spin room at a Las Vegas debate. Who among us can remember every hand shaken, every appointment kept, every 30-year-old underling plotting a backroom conversation with Vladimir Putin to acquire dirt on a political opponent?

Certainly not Attorney General Jeff Sessions.

Since his confirmation hearing in January, the former Alabama senator has faced dozens of hours of questioning under oath about the recent particulars of his career, his work as a surrogate on the Trump campaign, and his knowledge of any interactions between Trump campaign staffers and Russian operatives. Along the way, some fairly crucial details seem to have slipped his mind.

During this week's House Judiciary Committee hearing, the attorney general's peculiarly porous memory inspired much frustration among members of Congress eager to pin Sessions down on critical facts relating to Russian efforts to tamper with the 2016 election. In his questioning, representative Hakeem Jeffries of New York noted that over the course of three hearings, Sessions had said "I don't recall," in some form, upwards of 85 times.

Some of that count includes duplicates, cases where Sessions answered the same question two or more times. But we checked the record and found 47 distinct instances in which Sessions conveniently drew a blank, including occasions where his answers changed slightly. Funny how that happens. Here's everything Jeff Sessions has forgotten under oath this year, along with some especially baffling direct quotes:

Senate Judiciary Committee Confirmation Hearing

January 10, 2017

1. Why he voted against the Lilly Ledbetter Act, which extended the statute of limitations on pay discrimination cases.

2. Whether he remembers why the Lilly Ledbetter Act extended the statute of limitations; women often don't know they're experiencing pay discrimination until long after they receive their first paycheck. ("My memory is not that good.")

3. Whether he personally handled three voting rights cases, which he listed among the 10 most significant litigated matters he’d personally handled, despite three attorneys stating that he had no “substantive involvement" in them. ("Well, look, it was 30 years ago. And my memory was of this nature, and my memory was my support for those cases.")

4. Whether Trump’s surrogates and intermediaries for the Russian government had a continuing exchange of information during the campaign (they did!).

Senate Intelligence Committee Hearing

June 13, 2017

5. Whether he spoke to Russian officials during an event at the Mayflower Hotel in April 2016. ("I did not have any private meetings, nor do I recall any conversations with any Russian officials at the Mayflower hotel.")

6. Whether he interacted with the Russian ambassador, Sergey Kislyak, in passing.

7. Whether he remembers Kislyak being at the Mayflower Hotel.

8. Whether he remembers having a conversation with Kislyak at the Mayflower Hotel.

9. Whether he met with any other government officials in his capacity as a campaign surrogate. ("No. I've racked my brain to make sure I could answer those questions correctly and I did not. I would just offer for you that the—when asked about whether I had any meetings with Russians by the reporter in March, we immediately recalled the conversation and the encounter I had at the convention and the meeting in my office and made that public. I never intended not to include that. I would have gladly have reported the meeting and encounter that may have occurred and some say occurred in the Mayflower if I had remembered it or if it actually occurred, which I don't remember that it did.")
