Lisa Page, the former F.B.I. lawyer who became a frequent target of President Trump after criticizing him in text messages during his candidacy in 2016, ended nearly two years of public silence in an interview with The Daily Beast published on Sunday.

Since her text messages were made public in 2017, Ms. Page has often been singled out by Mr. Trump, who has brought up her name at political rallies and in dozens of tweets.

“It’s like being punched in the gut,” Ms. Page said in her interview last month with the writer Molly Jong-Fast. “My heart drops to my stomach when I realize he has tweeted about me again. The president of the United States is calling me names to the entire world. He’s demeaning me and my career. It’s sickening.”

Ms. Page, who worked for the F.B.I. on both the Clinton email and Russia investigations, criticized Mr. Trump during his candidacy in text exchanges with another bureau official, Peter Strzok, an agent with whom she was having an extramarital affair.
