Much of what Donald Trump vows to accomplish will land on the desk of Jeff Sessions, if he's confirmed as attorney general.
Restricting immigration. Imposing tougher criminal justice policies. And deciding the fate of the $85.4 billion proposed merger between AT&T and Time Warner, which President-elect Trump continues to oppose.
Implementing that agenda will require undoing a range of Obama-era policies that offered a gentler approach to enforcing immigration than the senator advocates, tolerance for the booming market in legal marijuana and an overhaul of sentencing.
It's a huge opportunity for the 70-year-old Alabama native who took a gamble backing Trump early in the primaries and is now on the cusp of becoming the nation's top law enforcement officer. With his Senate confirmation hearings beginning on Tuesday, the question is how many Democrats will vote against Sessions to protest the changes he's sure to make, knowing they will fall short of blocking the nomination unless some of his fellow Republicans turn against him.
"The new job he's seeking is one that requires a much bigger view of the world than any one of us would have as a United States senator," said Sen. Dick Durbin, D-Ill., who has served alongside Sessions on the Judiciary Committee and said he plans to ask tough questions.
Jefferson Beauregard Sessions III was a federal prosecutor in his home state and served as its attorney general before winning election to the Senate in 1996.
Long one of the Senate's more conservative members, Sessions' public record — including allegations of racist comments that scuttled his nomination to a federal judgeship in the 1980s — gives foes plenty of fodder. His hearing will be among the first for Trump's Cabinet picks and may provide an early indication of how easy or hard subsequent battles will be.
Opposition to Sessions centers largely on issues of civil rights.
