WASHINGTON — President Barack Obama has attended a Democratic Party fundraiser that was closed to media coverage.

Officials say about two dozen supporters were expected at Thursday's event at the Jefferson Hotel, a few blocks north of the White House.

Tickets cost $32,400 a pop, which means Obama filled the Democratic National Committee's coffers with nearly $400,000.

Officials say media coverage was not allowed because Obama was not making any formal remarks.

Across the street from hotel, several dozen people demonstrated against the Keystone XL oil pipeline. They chanted and held signs, including one that said, "Reject Keystone XL, No Tar Sands."
