The Washington Post reported Monday that spokesman Matt Verghese says Brown is expected to make a full recovery.
His office said in a statement that Brown had experienced dizziness and nausea shortly after returning home from the funeral of Kamenetz. His wife, Karmen Walker Brown, called 911.
The newspaper says the first-term congressman was taken to University of Maryland Prince George's Hospital Center, admitted for two nights and released Sunday. The 56-year-old is recovering at home and has not set a definite date for his return to Capitol Hill.
Brown was elected to Congress in 2016 after winning a six-way Democratic primary.
