Police said earlier Thursday that the shooter is dead, Douglas County Sheriff John Hanlin said the shooter and police had exchanged gunfire, but he did not confirm the number of fatalities or the kind of weapon that was used in the shooting.
Obama's statement is the 15th time during his presidency that he has responded to a mass shooting, according to CBS' Mark Knoller.
The last time he made a statement from the White House - on the shooting that left nine dead at an historically African-American church in Charleston, South Carolina - he lamented that he has had to "make statements like this too many times."
"There's been another mass shooting in America," Obama said as he opened his statement on Thursday.
"The reporting is routine, my response here at this podium is routine, the conversation in the aftermath of it - we've become numb to this."
According to The Washington Post, a full calendar week has yet to pass without a mass shooting during Obama's second term in office. According to the group Everytown for Gun Safety, Thursday's shooting in Oregon was the 142nd shooting incident since the 2012 massacre at Sandy Hook Elementary School in Newtown, Connecticut.
