US President Barack Obama has said "soul searching" is needed on how to reduce violence following a second mass shooting event in the US in a month.
Wade Michael Page, 40, killed six and injured three at a Sikh temple in near Milwaukee, Wisconsin on Sunday.
He was shot dead by police in the temple's car park during the attack.
Officials say they are investigating reports that Page had white supremacist links, and the FBI is treating the attack as possible domestic terrorism.
The temple attack follows a shooting in Aurora, Colorado at a midnight screening of the new Batman film on 20 July. Twelve people were killed and 58 were injured in the attack.
"All of us recognise that these kinds of terrible, tragic events are happening with too much regularity for us not to do some soul searching to examine additional ways that we can reduce violence, " Mr Obama said during an unrelated bill signing on Monday.
Mr Obama has pledged to work with members of both political parties and civic organisations to reach a consensus on the matter, but has not given details.
Debate on gun control issues has featured very little during the US presidential campaign, which has mainly focused on the economy, correspondents say.
