William Barr was sworn in as President Trump's second attorney general on Thursday, putting a new face atop the Justice Department who will assume oversight of special counsel Robert Mueller's investigation.

The Senate confirmed Barr in a largely party-line vote amid intense speculation that Mueller's probe into links between the Trump campaign and Moscow is wrapping up.

The investigation - and Barr's oversight of it - is likely to dominate his first weeks and possibly months as attorney general, depending on when Mueller submits his final report.

Here are five things to watch.

Mueller

DOJ leadership change

Clashes with congress

Trump-Barr relation

DOJ FBI treason.
