Sessions pleads hazy memory.

WASHINGTON (AP) — Attorney General Jeff Sessions on Tuesday displayed a hazy memory of the Trump campaign's discussions about and dealings with Russians in the 2016 election, denying he ever lied to Congress about those contacts but blaming the chaos of the race for fogging his recollections.

During more than five hours of testimony to Congress, Sessions sought to explain away apparent contradictions in his earlier accounts by citing the exhausting nature of Donald Trump's upstart but surging bid for the White House. He also denied under repeated questioning from Democrats that he had been improperly influenced in his decision making by Trump.

But after saying under oath months ago that he was unaware of any relationship between the campaign and Russia, Sessions acknowledged for the first time that the arrest of a low-level campaign adviser reminded him after all of a meeting at which the aide, George Papadopoulos, proposed setting up a get-together between Trump and Russian President Vladimir Putin.

"After reading his account and to the best of my recollection," Sessions told the House Judiciary Committee, "I believe that I wanted to make clear to him that he was not authorized to represent the campaign with the Russian government or any other foreign government for that matter.

"But I did not recall this event, which occurred 18 months before my testimony of a few weeks ago," he added, "and I would gladly have reported it had I remembered it because I pushed back against his suggestion that I thought may have been improper."

Papadopoulos was arrested by the FBI and pleaded guilty last month to lying to authorities about his own foreign contacts during the campaign. That guilty plea came in a wide-ranging criminal investigation led by former FBI Director Robert Mueller, who as the Justice Department's special counsel is looking into whether the Trump campaign coordinated with Russia to sway the outcome of the 2016 presidential election and into whether the firing of James Comey as FBI director was an effort to obstruct justice.

During the Trump campaign, Sessions, then an Alabama senator, served as a key surrogate for the Republican candidate and was asked to lead a foreign policy advisory council on which Papadopoulos served.

Yet the attorney general has struggled since January to move past questions about his own foreign contacts and about his knowledge of Russian outreach efforts during the election efforts.

After saying at his confirmation hearing that he had not communicated during the campaign with any Russians, he recused himself weeks later from the Justice Department's investigation into election meddling after acknowledging two previously undisclosed encounters with the Russian ambassador to the United States.

Each congressional hearing since then, including Tuesday's, has focused on Sessions' own recollections about the campaign.

Those questions have only deepened since the guilty plea last month of Papadopoulos and recent statements to congressional investigators by another foreign policy adviser, Carter Page, who has said he alerted Sessions last year about a trip he planned to take to Russia during the campaign.

Sessions insisted Tuesday that he did not recall that conversation with Page and appeared incredulous at times that he could be expected to remember the details of conversations from more than a year ago. Though he acknowledged the conversation with Papadopoulos, he said they were not in regular contact.

"In all of my testimony, I can only do my best to answer all of your questions as I understand them and to the best of my memory," Sessions said. "But I will not accept, and reject, accusations that I have ever lied. That is a lie."

Sessions insisted that his story had never changed and that he had never been dishonest. But he also suggested to the committee that it was unfair to expect him to recall "who said what when" during the campaign.

"It was a brilliant campaign, I think, in many ways, but it was a form of chaos every day from day one," Sessions said. "We traveled some times to several places in one day. Sleep was in short supply and I was still a fulltime senator ... with a very full schedule."

The oversight hearing divided along stark partisan lines.

Republicans, buoyed by the announcement a day earlier that the Justice Department might be open to a new special counsel to investigate an Obama-era business transaction that Trump himself has railed against, repeatedly challenged the underpinnings of Mueller's investigation.

Democrats, meanwhile, grilled him on the evolving explanations about how much he knew of communication during the campaign between Trump associates and Russian government intermediaries.

On Monday, the Justice Department said Sessions had directed federal prosecutors to look into whether a special counsel might be merited to investigate allegations that the Clinton Foundation benefited from a uranium transaction involving a Russia-backed company during the Obama administration.

On Tuesday, Sessions said that any such review would be done without regard to political considerations and said the appointment of a special counsel would require a "factual basis" and meet appropriate standards.

"A president cannot improperly influence an investigation," Sessions said in response to questions from the committee's top Democrat, Rep. John Conyers of Michigan.

"And I have not been improperly influenced and would not be improperly influenced," he added. "The president speaks his mind. He's bold and direct about what he says, but people elected him. But we do our duty every day based on the law and the facts."
