Sen. Kelly Ayotte (R-N.H.) on Sunday called for "tougher sanctions" against Russia for its actions in Ukraine, saying the United States cannot wait until after the upcoming Ukrainian elections to ratchet up its punishment.

"It'll be too late at that point," Ayotte said on "Fox News Sunday." "We already see the playbook of what happened in Crimea happening in eastern Ukraine."

The United States has already implemented limited economic and diplomatic sanctions against Russia, but Ayotte said Moscow "is not getting the message."

Rep. Adam Schiff (D-Calif.), who also appeared on the show, agreed that tougher sanctions are needed in light of the growing crisis in Ukraine. He added that the United States needs to focus on support from European allies.

"It's going to affect their economy much more than ours," he said. "Any sectoral sanctions that we administer without the Europeans aren't going to be effective. Our job is to get them on board."
