JEFFERSON CITY, Mo. -- Kentucky Sen. Rand Paul is coming to the aid of Missouri Senate candidate Todd Akin with a new advertising campaign.

Paul's political action committee plans to begin running an ad today against Democratic Sen. Claire McCaskill.

The one-minute ad criticizes McCaskill's vote against an amendment Paul sponsored last month that would have blocked foreign aid to Egypt, Libya and Pakistan.

Paul's committee is running similar ads against Democratic senators in several states.

Akin, a Republican congressman from suburban St. Louis, also called for the U.S. to suspend aid to Egypt after a recent attack on the U.S. embassy.

McCaskill saying the U.S. should be mindful of the consequences of suspending foreign aid during an already tense situation in the Middle East. Her campaign notes just 10 senators voted for Paul's amendment.
