Lawmakers, including Al Franken of Minnesota and Patrick Leahy of Vermont, have asked the FBI to investigate and to determine if Sessions committed perjury when he denied having had meetings with Russians.
Feinstein acknowledged she "would have a queasy feeling, too" if Comey's testimony was true that Lynch, as President Barack Obama's attorney general, had directed him to describe the FBI probe into Clinton's email practices as merely a "matter" and to avoid calling it an investigation.
