WASHINGTON (AP) " The Latest on the 2020 presidential election (all times local):

7:10 p.m.

Republican Mike Pence will press the Trump campaign's 'law and order' message at the vice presidential debate against Democrat Kamala Harris.

Pence's guests in the debate hall Wednesday night will include Ann Marie Dorn, the widow of retired St. Louis police captain David Dorn, who was shot to death on June 2 after a violent night of protests.

President Donald Trump and his campaign have seized on the scattered violence that has broken out amid otherwise largely peaceful protests demanding racial justice. Trump has wrongly claimed that such violence has been condoned by his Democratic rival, Joe Biden, and has warned it will continue if Biden wins in November.

Ann Marie Dorn also spoke at the Republican National Convention.

Pence will also be joined by the parents of Kayla Mueller, a humanitarian aid worker who was taken captive and killed by Islamic State militants.

HERE'S WHAT ELSE IS HAPPENING:

7 p.m.

Two Utah women will attend Wednesday's vice presidential debate in Salt Lake City as guests of Democrat Kamala Harris.

Angela Romero is a state representative who also works in local government in Salt Lake City, overseeing the Division for Youth and Family programs. The campaign says Romero is focused on supporting families and local businesses affected by the coronavirus pandemic.

Deborah Gatrell is a veteran and teacher who is running for a seat on the Salt Lake County Council. She is a Blackhawk pilot who served in the Utah National Guard and was deployed to the Middle East.

The campaign says the two women represent the hard-working Americans that a Joe Biden-Kamala Harris administration would fight for.

President Donald Trump's campaign is dialing back on advertising in Midwestern states that secured his first term in office.

Data from the ad tracking firm Kantar/CMAG shows Trump's campaign has canceled about $3.3 million in advertising planned for Iowa and Ohio this week. But details provided from Democratic advertising trackers reveal the phenomenon is more widespread.

The data shows Trump is running $1.3 million in advertising this week in Michigan, where Democratic presidential nominee Joe Biden is spending $2.9 million. In Wisconsin, Trump is spending $229,000 compared to Biden's $2.5 million. And in Minnesota, a longtime Democratic stronghold where Trump hoped to make inroads, Biden is outspending him $1 million to Trump's $289,000 this week.

The ad decisions by Trump's campaign are puzzling.

He amassed a massive campaign bank account after his election, but Biden has outraised him in recent months. Many Republican donors have been alarmed by the campaign's exorbitant spending on things unrelated to winning, including lavish payments to campaign consultants and surrogates.

President Donald Trump has returned to the Oval Office for the first time since he was diagnosed and hospitalized with COVID-19.

Spokesperson Brian Morgenstern confirmed that the president returned to the Oval Office on Wednesday. He has been convalescing in the White House residence since he returned from a three-night hospital stay on Monday evening.

Trump is likely still contagious with the virus.

A Marine was posted outside the West Wing, signifying the president was in the Oval Office.

White House officials say they have put additional safeguards in place to protect staff who may interact with the president, including requiring full personal protective equipment.

Morgenstern says Trump is being briefed on stimulus talks and a potentially devastating hurricane heading toward the Gulf Coast.

Vice President Mike Pence will be joined in the debate hall by several special guests, including the parents of Kayla Mueller, the humanitarian aid worker who was killed by Islamic State militants.

Their presence Wednesday night is intended to highlight action taken by President Donald Trump, including the killing of the group's leader, Abu Bakr al-Baghdadi, in contrast to the approach taken by the Obama administration, which Mueller's parents have criticized.

Carl and Marsha Mueller were featured in Trump's State of the Union address earlier this year and spoke at the Republican National convention. In their speech, they asserted that, had Trump 'been president when Kayla was captured, she would be here today.'

The 26-year-old Mueller was taken captive in August 2013 after leaving a Doctors Without Borders hospital in Aleppo, Syria.

The debate comes the same day that two Islamic State militants " dubbed part of the 'the Beatles' because of their British accents "- were brought from Britain to the U.S. to face charges in connection with the deaths of American hostages, including Kayla Mueller.

Kamala Harris has again tested negative for the coronavirus.

The campaign reported her results on Wednesday, less than 12 hours before she is scheduled to debate Vice President Mike Pence. She took the test Tuesday.

Pence also tested negative on Tuesday, according to the White House.

Harris and Pence will appear on stage at the University of Utah for a 90-minute debate. Both candidates will have plexiglass around them as an additional precaution. That was requested by the Biden-Harris campaign, and Pence's team objected.

Harris also tested negative for the virus on Monday.
