Secretary Mayorkas tests positive for COVID-19
Department of Homeland Security Secretary Alejandro Mayorkas has tested positive for COVID-19, a DHS spokeswoman confirmed to ABC News.
Mayorkas, who is fully vaccinated, "is experiencing only mild congestion," a statement said.
Mayorkas will work from home, the statement said. Contact tracing is underway.
There were no major White House officials deemed to be close contacts. "No White House principal has been determined to be a close contact of Secretary Mayorkas, given that the most recent contact was at the outdoor National Peace Officers’ Memorial Service, which took place outside of the 48-hour close contact window,” the White House said in a statement.

Delta doesn't cause more severe illness than prior variants: CDC
A new report from the Centers for Disease Control and Prevention suggests that although the delta variant is significantly more transmissible than prior variants, it is not more likely to lead to hospitalization.
Instead, the dramatic uptick in hospitalizations seen during the summer's delta surge was fueled by the highly transmissible variant spreading easily among mostly unvaccinated people, the CDC said.
The report, which analyzed COVID-19 hospitalization data from 14 states, also found that the proportion of people aged 18 to 49 hospitalized with delta increased "significantly" in July and August to 35.8% of all hospitalizations compared to 24.7% from January to June of this year. This was likely due to lower vaccination rates among younger people, the CDC said.
