Before the Senate adjourned for the November elections, Paul got a vote on his bill to cut off U.S. foreign aid to Egypt, Libya and Pakistan, but the measure failed on an 81-10 vote.

Paul’s PAC is running similar ads this week in Missouri and Florida, where Sens.

When Paul’s bill was being debated on the Senate floor, he repeatedly said the American people agreed with him that foreign aid shouldn’t be sent to countries that “don’t act like our friends” — a reason why his colleagues didn’t want to be on the record voting against his bill.

But 30 Republican senators voted with Democrats against Paul’s bill, some saying it would hurt relations with Israel and possibly jeopardize peace in the Middle East.

The Telegraph Forum said Justin Barasky, a spokesman for Brown's campaign, blasted the RANDPAC ads.
