WASHINGTON — Attorney General William P. Barr did not plan to get a coronavirus test on Monday after receiving negative results from four tests and was likely to return to work at the Justice Department this week, his spokeswoman said.
Mr. Barr, who had attended an event at the White House on Sept. 26 linked to the outbreak, quarantined himself over the weekend and was at home on Monday with no symptoms, said the spokeswoman, Kerri Kupec.
She said that Mr. Barr would get tested on Tuesday and was likely to return to the office on Wednesday. That would be before the end of the 14-day quarantine period recommended by the Centers for Disease Control and Prevention as well as Justice Department guidelines, but Ms. Kupec said the attorney general was considered a critical worker exempt from the C.D.C. guidelines.
Ms. Kupec said Mr. Barr, 70, “routinely wears masks and takes a variety of precautions” at the office.
Some department employees expressed anger at Mr. Barr’s decisions, saying that his leadership example indicated that he did not take the threat of the virus seriously, according to five employees who would not be named discussing Mr. Barr’s approach to the virus for fear of retribution.
Asked about the criticism, Ms. Kupec said that as the nation’s chief federal law enforcement officer, Mr. Barr was considered a critical worker under the C.D.C. guidance. It says that essential workers “may be permitted to continue work following potential exposure to Covid-19, provided they remain asymptomatic and additional precautions are implemented to protect them and the community.”
Precautions include wearing a mask at all times in the workplace, social distancing, regular temperature checks and continued testing.
“Even with this flexibility, out of an abundance of caution, he has remained home since Friday other than to get tested and attend the meeting at the Justice Department on Friday morning,” Ms. Kupec said.
In President Trump’s own battle with the coronavirus, his oxygen levels have dropped and he has taken experimental drugs and a steroid. He left Walter Reed National Military Medical Center on Monday.
After Mr. Trump revealed early on Friday that he had tested positive for the virus, Mr. Barr took a rapid test each day and took an additional diagnostic test called a PCR test, and made their results public. Through the weekend, his tests came back negative, Ms. Kupec said.
Mr. Barr also decided to reduce his schedule to one meeting on Friday and to self-quarantine at home over the weekend, she said.
Ms. Kupec said on Monday that Mr. Barr had not had any contact with Mr. Trump for nine days, when both men attended a reception at the White House for the president’s Supreme Court nominee, Judge Amy Coney Barrett.
Several Republican leaders and others who attended the reception have since learned they have the virus, including Mr. Trump; the first lady, Melania Trump; Senators Mike Lee of Utah and Thom Tillis of North Carolina; John I. Jenkins, the president of
