Following a first night of programming focused on unity -- featuring a handful of Republican speakers and former first lady Michelle Obama -- Democrats continue their mostly virtual convention in Milwaukee Tuesday under the theme of "Leadership Matters" with primetime speeches from both the party's more established leaders and its younger stars.
"We'll hear from the leaders and the experts, the veterans and the activists, all those who seek to unite and not divide, and who step up -- not back down -- from a fight over what's right," the Democratic National Convention Committee said in a news release.
ABC News Live will kick off primetime coverage each day at 7 p.m. ET on the network's steaming news channel and primetime coverage will air from 10-11 p.m. ET each night of the convention on the ABC Television Network.

7:56 p.m. Trump: 'Not the best television I've ever watched'
President Trump was asked earlier Tuesday how he'd make his convention more lively than the DNC and he pointed to the Democrats' taped elements -- and noted the relatively poor broadcast ratings reported for the first night.
"Their ratings were very bad," he said at an event in Yuma, Arizona, with border officials. "They just announced their rating and I thought it was not the best television I've ever watched. It was brutal actually. No, their ratings were very bad."
The Hollywood Reporter noted that the ratings were down "considerably" since the 2016 conventions, but that it wasn't a surprise "given that much of the convention isn't taking place live and the general decline of linear TV viewing in the past four years."
Trump continued, "I think we're going to do great. Thursday night I'm doing it live, unlike Michelle Obama. I'm doing it live. And it'll be Thursday night, it'll be at the White House on the South Lawn and hopefully you'll enjoy it."

7:36 p.m. Colin Powell to speak at the DNC
Under the header of the Biden plan for national security, Colin Powell, a former chairman of the Joint Chiefs of Staff and secretary of state in President George W. Bush's administration, will join national security leaders who have served Democratic and Republican presidents to make their case for Joe Biden's steady, experienced leadership, according to the DNC.
"I support Joe Biden for the presidency of the United States," Powell says in a clip released by the DNC.
He goes on to reference Biden's son Beau, who served as an officer in the Army Judge Advocate General's Corps.
"Our country needs a commander in chief who takes care of troops, in the same way he would his own family," Powell says. "For Joe Biden, that doesn't need teaching. It comes from the experience he shares with millions of military families, sending his beloved son off to war and praying to God he would come home safe."
7:31 p.m. Cindy McCain to talk about the late-Sen. John McCain's friendship with Biden
Cindy McCain is set to appear at the DNC in a video segment - but only via audio - that details the "unlikely" friendship between former Vice President Joe Biden and her late husband, Sen. John McCain.
Convention officials released a clip of the segment, in which McCain says about the two, "They would just sit and joke. It was like a comedy show sometimes to watch the two of them."
The rest of the clip shares some personal details about the friendship between the two, from their younger days when they were on a different path to when those paths ultimately crossed.
"It was a friendship that shouldn't have worked. John, a former Navy pilot just released from a North Vietnamese prison. Joe, a young senator from Delaware," the narrator says in the preview clip. "But in the 1970s, Joe was assigned a military aide for a trip overseas."
"I was a Navy Senate liaison and used to carry your bags on overseas trips," John McCain says in the video, which is pulled from a 2016 clip from the Senate floor.
"The son of a gun never carried my bags. He was supposed to carry my bags there but he never carried my bags," Biden says, a clip from his 2017 speech at the Liberty Medal ceremony.
"John and Joe traveled thousands of miles together," the narrator says. "The families got to know each other, gathering for picnics in the Biden's backyard."
Cindy McCain wrote on Twitter that she was "honored" to accept an invite from the Biden team to be part of the video.
"My husband and Vice President Biden enjoyed a 30+ year friendship dating back to before their years serving together in the Senate, so I was honored to accept the invitation from the Biden campaign to participate in a video celebrating their relationship," McCain tweeted.
In 2019, about a year after McCain's death, Cindy McCain spoke with ABC News Chief White House Correspondent Jonathan Karl about the legacy of her late husband.
At that time, she said the current Republican Party is "not the party of Abraham Lincoln ... nor the party of Ronald Reagan."
"That was a tough torch to carry and, as John said, there were many lonely days because he always said what was on his mind," she told Karl.
McCain added that her husband "never did anything deliberately to be hurtful or anything. … I don't see anybody carrying that mantle at all, I don't see anyone carrying the voice -- the voice of reason."

7:20 p.m. Michelle Obama posts encouragement to her 'partner-in-crime' Jill Biden
Ahead of her remarks Tuesday, former first lady Michelle Obama penned a lengthy message of encouragement to her "partner-in-crime" Jill Biden on Instagram.

7:06 p.m. Roll call to begin in Alabama
"Roll Call Across America" will kick off in Alabama, with Rep. Terri Sewell delivering the delegation's votes from the Edmund Pettus Bridge in Selma, the site where Alabama state troopers attacked the late-Rep. John Lewis and other civil rights demonstrators in 1965 in an incident that became known as "Bloody Sunday," the Alabama congresswoman's office confirmed to ABC News.
Biden will be formally nominated as the party's presidential nominee during a 30-minute roll call featuring representatives for all 57 states and territories -- a usually long-winded process that can take hours.
This year, the roll call will include delegates, parents, teachers, small business owners, essential workers, activists and elected leaders inside businesses, living rooms and in front of iconic landmarks.
Two of the other locations where state delegations will cast votes to formally nominate Biden are the Frederick Douglass statue in Baltimore, Maryland and the "Welcome to Las Vegas" sign in Nevada.

7 p.m. An overview of the evening's program
Tuesday evening's program includes speeches from former President Bill Clinton, Senate Minority Leader Chuck Schumer and New York Rep. Alexandria Ocasio-Cortez, who was allotted just one minute. Some progressives view her speaking time as a slight by the establishment and a reflection of the broader disconnect between the national party and younger, more diverse voters -- a gap party leaders are hoping to close heading into November.
A group of 17 "rising stars" within the party -- including former Georgia gubernatorial candidate Stacey Abrams, Pennsylvania Rep. Conor Lamb and Texas Rep. Colin Allred -- are slated to deliver the night's keynote address meant to capture the party's "diversity of ideas and perspectives."
Former Vice President Joe Biden's formal nomination by a pre-recorded roll call vote from all 57 states and territories is also set for Tuesday.
