In just one day, Vice President Kamala Harris and former President, Donald Trump will face off for the first time on the debate stage with the countdown on both campaigns gave a look into their preparations. A B C's Christian Cordero has the latest from Washington this morning. The race to the White House is closing in on its landmark stop at the ABC news debate in Philadelphia. Now just one day away, Vice President Kamala Harris paused her debate prep over the weekend. While in Pittsburgh, the vp's team has held mock debates with full TV lighting. It's her first time going face to face against former president Donald Trump and her first president debate. It is Trump's seventh Trump so far has downplayed his debate, prep strategy, no mock debates, no studio lighting and appearing to lower expectations over the weekend. If I destroy her in the debate, they'll say Trump suffered a humiliating defeat tonight. Trump is holding informal policy sessions with advisers including representative Matt Gates and former Representative Tulsi Gabbard who won challenged Harris on the debate stage in 2019 on social media. A new threat from the former president repeating baseless claims about the 2020 election and vowing to prosecute those he accuses of fraud, Trump writing when I win, those people that cheated will be prosecuted to the fullest extent of the law which will include long term prison sentences so that this depravity of justice does not happen again on the Harris campaign website today, a long awaited issues page touching on the vice president's stance on issues related to the economy and foreign policy While her running mate, Tim walls doubled down on reproductive rights over the weekend. So my pro tip opponent on the other side is quit talking about women's childbearing issues, quit talking about it because no one cares what your thoughts are. Christian Cordero ABC News Washington. The debate is tomorrow in Philadelphia at the National Constitution Center that starts at 9 p.m. right here on whas 11 and you can watch our news at 11 after that debate.
