White House spokesman Josh Earnest says President Obama will likely sign a bill slapping more sanctions on Russia by week's end.

Earnest told a briefing that the costs on Moscow will continue to increase as a result of Russian incursions in Ukraine.

He said international sanctions that have already been imposed are taking a bite out of Russia's economy. The U.S. legislation also contains aid for Ukraine.

Earnest said Russia will continue to pay a price for trampling on international rules and for not respecting the territorial integrity of Ukraine.

Earnest stepped around questions about whether Russian President Vladimir Putin may become even more aggressive in response to the growing sanctions.  (Metro Networks Inc.)
