Former president Bill Clinton will speak about President Obama's signature health care law at an event Sept. 4 in Little Rock, Ark.

Clinton will address Obamacare and health care policy in general at a speech at the Clinton Presidential Center, according to the Clinton Foundation.

The foundation says Clinton will speak about "the critical role a high quality, affordable and accessible health care system plays in the United States and any country's economic and social well being."

The speech will take place at 11 a.m. eastern time, and will be broadcast on the Clinton Foundation's Web site.

Key aspects of Obamacare are set to be implemented in the coming months, and leading to a renewed clash over its funding and its viability.

According to a White House official, who asked not to be identified because the speech has yet to take place, Clinton’s speech “will be the first of a number of high-profile events and speeches by administration officials and allies throughout the fall” aimed at boosting public awareness of the law.

Clinton will also headline other events “to raise public awareness around the law during the critical months for open enrollment,” the official wrote in an e-mail.

White House communications director Dan Pfeiffer said he looks forward to Clinton's remarks:

Excited to have President @BillClinton, once dubbed Secretary of Explaining Stuff, talk about the health reform law on 9/4 in Little Rock

Updated 11:49 a.m.: Notably absent next week at Clinton’s speech will be Sen. Mark Pryor (D-Ark.), who is facing one of the most difficult reelections of any Democratic senator. Pryor campaign spokeswoman Amy Schlesing said the senator won’t be in attendance, “because he has a previously scheduled engagement out of town that day.”

Republicans have been attacking Pryor on Obamacare. Clinton, a former Arkansas governor, raised money for Pryor's reelection campaign earlier this year.
