As Sens. John McCain, R-Ariz., and Barack Obama, D-Ill., engaged in their first one-on-one presidential debate Friday evening, ABC News looked into their claims and found they were not always entirely accurate.
Claim: Obama said he "pays for every dime" of his spending proposals.
Fact: The nonpartisan Tax Policy Center says that Obama's policies would increase the debt by $3.5 trillion over 10 years. The Tax Policy Center adds that McCain's policies would lead to an even bigger increase in the debt of $5.1 trillion.
Claim: Obama said that McCain "wanted to give oil companies another $4 billion."
Fact: McCain's tax proposal would give tax breaks to all corporations, not just oil companies. His proposal seeks to lower the corporate tax rate 10 percent.
Claim: Obama said "if you make less than $250,000 -- less than a quarter-million dollars a year -- then you will not see one dime's worth of tax increase."
Fact: Obama has called for higher taxes on income, capital gains and dividends for individuals making $200,000 per year. His tax plan imposes higher taxes on couples starting at $250,000 a year.
Claim: McCain suggested Adm. Mike Mullen called Obama's Iraq withdrawal plan "dangerous." Obama said, "That's not the case."
Fact: On "Fox News Sunday," Mullen was asked by Chris Wallace if setting a timeline for withdrawal along the lines of Obama's plan "could be dangerous." Mullen told Chris Wallace, "I think the consequences could be very dangerous in that regard."
Claim: McCain began tonight's debate by expressing his concerns for Ted Kennedy "who is now in the hospital."
Fact: While Ted Kennedy did go to the hospital briefly today for a minor seizure, the Kennedy family released a statement an hour before the debate began saying he was back at home, doing well and watching the debate.
Claim: McCain said Gen. Dwight Eisenhower wrote a resignation letter the night before the Normandy invasion in World War II.
Fact: Eisenhower wrote a letter taking full responsibility for the consequences of the invasion, but did not write a letter of resignation, according to the National Archives. See the letter here.
Claim: McCain said Obama voted for a tax increase on people who make $42,000 per year.
Fact: Obama voted "yes" on a Senate budget resolution that would raise the tax rate from 25 percent to 28 percent for single wage earners making $42,000 or more. However, budget resolutions are non-binding and do not affect tax rates.
Claim: McCain said he'd been criticized because he "called for the resignation of the chairman of the Securities and Exchange Commission."
Fact: McCain has been criticized in part for saying to reporters last Thursday, "If I were president today, I would fire him" -- something the president technically cannot do because the SEC is an independent agency.
Claim: McCain said that Obama did not understand that Pakistan was a "failed state" when Gen. Pervez Musharraf came to power.
Fact: Musharraf came to power in a military coup in 1999, deposing Prime Minister Nawaz Sharif. The institutions of government never stopped functioning.
Claim: Both men talked about the Iranian "Republican Guard."
