President Obama said Tuesday that if the hack into the Democratic National Committee’s email system ends up being tied to Russia, that fact wouldn’t significantly impact his relationship with Russian President Vladimir Putin.

“I think we’ve already got a lot of differences with Russia on a whole lot of issues,” he said during a press conference Tuesday with the prime minister of Singapore. “… If in fact Russia engaged in this activity, it is just one on a long list of issues that me and Mr. Putin talk about and one that I’ve got a real problem with.”
