How often have North Carolina's senators worked with John McCain?

A quick search of legislation filed in recent years shows a handful of bills which U.S. Sens. Elizabeth Dole and Richard Burr have cosponsored with the presumptive Republican presidential nominee.

Burr signed on to four McCain-sponsored bills: Imposing sanctions on the Burmese junta, creating a federal gas-tax holiday this summer, requiring illegal immigrants to pay back taxes before becoming citizens and designating a National Mentoring Month.

Dole signed on to the Burmese sanctions and the mentoring month as well as an amendment to name a military spending bill for Sen. John Warner, a Virginia Republican.

In addition, McCain signed on to two Dole bills: Recognizing the Lumbees as a tribe and awarding a Congressional Medal of Honor to Tony Blair.

He did not sign on to any Burr-sponsored bills.
