Obama calls Trump 'wannabe king' at Harris event

Democratic senators, led by Majority Leader Chuck Schumer and Senate Rules Committee Chair Amy Klobuchar, released a report Tuesday urging Americans to cast their ballots as soon as possible and warning that election results may not be known on Election Day.

"Just like 2020, Donald Trump and his allies continue to refuse to commit to accepting the results of the election if he loses while pushing dangerous and divisive rhetoric to sow discord and undermine confidence in our election process. Americans losing faith in the results of our elections doesn't just risk another January 6th but puts our very democracy at risk," Schumer said in a statement with the release of the report. "Senate Democrats remain committed to ensuring all Americans can vote without fear or intimidation."

The report details the early voting and mail-in ballot count procedures, including details on how and when some swing states count their ballots.

Using these details, the report asserts that "early vote counts may create the appearance that one particular candidate is ahead but that may change depending on whether in-person or mail-in vote totals are reported first. Americans should be prepared to reject misinformation and be patient about results in places where counting ballots may take longer."

Trump still refuses to accept that he lost the 2020 election and has encouraged voters to cast ballots for him on Nov. 5 so that his margin of victory is "too big to rig."

Former Wyoming Republican Rep. Liz Cheney will sit down with ABC News' Chief Washington Correspondent and Co-Anchor of "This Week" Jonathan Karl at the Detroit Economic Club on Tuesday afternoon.

Part of the event will be streamed on ABC News Live.

Karl's discussion with Cheney comes a day after she hit the campaign trail with Harris for a series of moderated conversations in the battleground states of Pennsylvania, Michigan and Wisconsin, in which they sought to appeal to white suburban women who vote Republican.

Trump will hold a roundtable at the Latino Summit at his Doral golf club in Miami. The event was postponed because of Hurricane Milton and comes as the former president seeks to eat away at Harris' edge with Hispanic voters, particularly males.

Trump will later head to Greensboro, North Carolina, for a rally.

Harris, notably, has no public events scheduled for Tuesday, spending her afternoon instead doing interviews with NBC News and Telemundo.

Former President Barack Obama joins Minnesota Gov. and Democratic vice presidential nominee Tim Walz for a rally in Madison, Wisconsin.

Harris and Trump are preparing for a flood of legal activity before and after the election after the former president launched an avalanche of lawsuits seeking to overturn his loss in 2020.

Earlier this year, the Republican National Committee and the Trump campaign announced what they described as an "historic" "election integrity" program that an RNC official said in recent months has engaged in over 130 election lawsuits across 26 states, and recruited approximately 5,000 volunteer attorneys who are ready to be activated on Election Day.

Democrats, for their part, have intervened in "dozens of baseless Republican lawsuits to debunk their lies and defeat them in court," according to an internal memo prepared by Harris' chief attorney, Dana Remus.
