CEDAR RAPIDS, Iowa (AP) — Republican presidential candidate John McCain said Thursday he would fire Securities and Exchange Chairman Christopher Cox if he were president, accusing the former GOP congressman of betraying the public's trust.

McCain criticized President Bush's choice to lead the federal agency that regulates U.S. stocks and securities as he and Democratic rival Barack Obama tried to win over voters anxious to hear how the next president would prevent the sort of financial tremors that have shaken the financial industry this week.

Economic issues traditionally favor Democrats and were expected to be especially potent for Obama in an election cycle that follows eight years of a Republican White House and a Congress usually dominated by the GOP.

WASHINGTON (AP) — Hackers broke into the Yahoo! e-mail account that Republican vice presidential candidate Sarah Palin used for official business as Alaska's governor, revealing as evidence a few inconsequential personal messages she has received since John McCain selected her as his running mate.

"This is a shocking invasion of the governor's privacy and a violation of law. The matter has been turned over to the appropriate authorities and we hope that anyone in possession of these e-mails will destroy them," the McCain campaign said in a statement.

The Secret Service contacted The Associated Press on Wednesday and asked for copies of the leaked e-mails, which circulated widely on the Internet. The AP did not comply.

CHICAGO (AP) — Democratic presidential hopeful Barack Obama's campaign announced Friday that he will campaign with former rival Hillary Rodham Clinton next week, a step toward unifying a fractured Democratic Party after a bruising primary fight.

Obama's campaign said in a brief e-mail that said the two senators and former opponents will campaign together for the first time on Friday, June 27, and more details would be forthcoming.

A day earlier, Obama and Clinton also plan to meet in Washington with some of her top contributors in an effort to calm donors who remain frustrated with Obama's presidential campaign. The former first lady will introduce Obama to her financial backers.

WASHINGTON (AP) — Democrat Barack Obama's campaign said Thursday that Michelle Obama never used the word "whitey" in a speech from the church pulpit as it launched a Web site to debunk rumors about him and his wife.

The rumor that Michelle Obama railed against "whitey" in a diatribe at Chicago's Trinity United Church of Christ has circulated on conservative Republican blogs for weeks and was repeated by radio talk show host Rush Limbaugh. The rumor included claims of a videotape of the speech that would be used to bring down Obama's candidacy this fall.

"No such tape exists," the campaign responds on the site, www.fightthesmears.com. "Michelle Obama has not spoken from the pulpit at Trinity and has not used that word."

WASHINGTON (AP) — Jim Johnson, a manager of Democrat Barack Obama's vice presidential search team, resigned Wednesday amid criticism over his personal loan deals.

"Jim did not want to distract in any way from the very important task of gathering information about my vice presidential nominee, so he has made a decision to step aside that I accept," Obama said in a statement. "We have a very good selection process under way, and I am confident that it will produce a number of highly qualified candidates for me to choose from in the weeks ahead. I remain grateful to Jim for his service and his efforts in this process."

ST. PAUL, Minn. (AP) — Cheered by a roaring crowd, Sen. Barack Obama of Illinois laid claim to the Democratic presidential nomination Tuesday night, taking a historic step toward his once-improbable goal of becoming the nation's first black president. Hillary Rodham Clinton maneuvered for the vice presidential spot on his fall ticket without conceding her own defeat.

"America, this is our moment," the 46-year-old senator and one-time community organizer said in his first appearance as the Democratic nominee-in-waiting. "This is our time. Our time to turn the page on the policies of the past."

CHICAGO (AP) — History within his reach, Barack Obama was primed to claim the Democratic presidential nomination Tuesday or soon after as voters in Montana and South Dakota bring his months-long contest with dogged rival Hillary Rodham Clinton to a close. Clinton appeared ready to bow to the inevitable and spare the party an even more protracted fight.

Clinton campaign chairman Terry McAuliffe said Tuesday that once Obama gets the majority of convention delegates, "I think Hillary Clinton will congratulate him and call him the nominee."

WASHINGTON (AP) — Democratic Party leaders agreed Saturday to seat Michigan and Florida delegates with half-votes at this summer's convention with a compromise that left Barack Obama on the verge of the nomination but riled Hillary Rodham Clinton backers who threatened to fight to the August convention.

"Hijacking four delegates is not a good way to start down the path of party unity," said adviser Harold Ickes.

Clinton's camp maintains she was entitled to four additional Michigan delegates.
