For Atty. Gen. Jeff Sessions, questions about the Trump campaign and Russia have become a nagging headache that won’t go away.

For the record: An earlier version of this article gave the wrong location for a meeting in March 2016 attended by then-Sen. Jeff Sessions and George Papadopoulos. It was held in Washington, not New York.

On Tuesday, the nation’s highest lawman will face another grilling on Capitol Hill, this time prompted by claims in court documents and congressional testimony that he was told of at least two aides’ meetings with Russian officials — despite his claim last month that he was unaware of any such contacts.
