Donald Trump’s pick for attorney general, Pam Bondi, will face sharp questioning from Democratic senators at a confirmation hearing expected to center on concerns the Republican president-elect will look to use the Justice Department’s powers to seek retribution against his adversaries.

During one contentious exchange in her confirmation hearing, Democratic Sen. Alex Padilla of California asked Bondi whether she found any evidence of widespread fraud. The senator repeatedly pressed her for a yes or no answer but did not give Bondi an opportunity to expound on her time with the campaign.
