Mr. Talley demurred. “It would be inappropriate for me as a nominee to comment on the advisability of any nomination,” he wrote.
Senator Dianne Feinstein of California, the ranking member of the committee, asked if Mr. Talley had ever argued a motion in Federal District Court, given that he had never tried a case. He had not.
Ms. Feinstein also pointed to Mr. Talley’s prolific social media presence before his nomination. He once referred to Hillary Clinton as “Hillary Rotten Clinton” on his public Twitter account, which is now private.
In 2013, he wrote on his blog that armed revolution was an important defense against tyrannical government. Ms. Feinstein asked in her written questions when Mr. Talley believed it would become appropriate for American citizens to participate in an armed uprising against the government.

Senator Lindsey Graham, Republican of South Carolina, in 2012 had praised the bar association’s practice of evaluating judicial nominees as an important way to…
