The second presidential debate was expected to be especially contentious after the revelation of a video in which Republican Donald Trump made lewd comments about women, and the leak of hacked emails from Hillary Clinton that suggest she held positions on several issues that are contrary to what she has said recently on the campaign trail.And those expectations were met.Trump entered into the debate Sunday night at Washington University in St, Louis in serious need of a strong performance.Some top Republicans are urging Trump to drop out of the race after the 2005 tape surfaced in which he made lewd comments about women, saying he can grope them because he is a "star."Trump apologized for the candidly-recorded comments in 2005, calling it locker-room talk and that he is not proud of it. He said he is embarrassed and hates what he said, insisting he has great respect for women and that it is time to talk about more important things. He also denied ever sexually assaulting a women just because he felt his celebrity status allowed him to. Clinton said while she has disagreed with the policies of previous Republican candidates, this is the first time she has questioned a candidate's fitness to serve as president. Despite his apology, Clinton said the tape shows exactly who Trump is. She also pointed out that Trump has insulted and denigrated minorities, Muslims, and prisoner of war. Trump accused Hillary Clinton's husband, former President Bill Clinton, of sexually abusing women in the White House and said as a defense attorney, Hillary defended the accused rapist of a 12-year-old girl. Trump also said he would appoint a special prosecutor to investigate Clinton's 33,000 missing e-mails, saying if he were in charge, Clinton would be in jail.Fix or repeal Obamacare?Trump and Clinton also battled over the future of President Barack Obama's signature health care law. Clinton, acknowledged that the law has raised premiums and price of drugs, but she vowed to fix it, unlike Trump, who promised to replace it. Clinton said she would appoint Supreme Court justices who have "real world experience" trying cases, while Trump said his choices wold be people who are well thought of and would respect the construction. Clinton hit out at Trump over taxes. Asked by an audience member what they would do to get the wealthiest Americans to pay their fair share, Clinton said it was amusing to hear the man who probably has not paid taxes in 20 years. Trump said he is was proud of knowing the tax code well enough to take advantage of it and pointed out that some of Clinton's wealthy donors have done the same thing.SyriaClinton said she would not put ground forces into Syria, saying that would not be a smart strategy.She called Aleppo a catastrophic situation, and that Russia is determined to destroy the city in an effort to keep Bashar al-Assad in power, and supports efforts to hold Russia and the Syrian regime accountable for war crimes in the ongoing Syrian civil war.Trump said he disagrees with his running mate, Mike Pence, who called for strikes on Syrian government targets, but Trump saved most of his comments on Syria for President Barack Obama.Trump said the world laughed when Obama declared a"line in the sand" in Syria. He also said Clinton does not know who the rebels are in Syria, and questioned who would get the weapons.
