President Donald Trump emerged from the White House on Wednesday, visiting Arlington National Cemetery in Virginia to mark Veterans Day - his first official public appearance since last week, other than two golf outings - after days of pushing his unsubstantiated claims of voter fraud from inside the executive mansion.

In a new, flagged Twitter post on Wednesday, Trump alleged there was "a mountain of corruption & dishonesty" in Pennsylvania and, again, falsely stated: "We win!"

In Philadelphia, President-elect Joe Biden - who has called Trump's failure to concede an "embarrassment" - visited the Korean War Memorial at Penn's Landing.

Biden also planned meetings with advisers on Wednesday who are helping him prepare to take office in January, even as the Trump administration refused to cooperate with Biden's team, which has been unable to move into federal government office space or tap funds to hire staff as a result.

Raising even more concern among Democrats was Trump's move to install loyalists in top positions at the Pentagon this week. After Trump fired Defense Secretary Mark Esper, the Pentagon's top policy adviser resigned, allowing that post to be filled by Anthony Tata, a retired Army brigadier general who has promoted conspiracy theories and called former President Barack Obama "a terrorist leader."

Meanwhile, Trump's campaign is forging ahead with its long-shot litigation strategy to try to reverse the results of the election, filing a fresh lawsuit in Michigan on Wednesday to try to block the state from certifying its results.

Trump trailed by more than 148,000 votes in Michigan, according to unofficial vote totals.

Trump's campaign has also filed suit in Pennsylvania to halt the certification of that state's results, alleging lax oversight of mail-in voting. According to new data out on Wednesday, Biden's current lead in Pennsylvania is greater than the margin needed to trigger a recount.

Judges have tossed out several Trump election lawsuits, and legal experts say the litigation has little chance of changing the election outcome... nor do recounts.

RAFFENSPERGER: "...a full, by-hand recount..."

In Georgia, Secretary of State Brad Raffensperger said a recount of all ballots was expected to begin this week and would be certified by a Nov. 20 deadline.

He vowed to look into allegations of voter fraud, but maintained that election officials and their staff had worked hard to bring fair and accurate counts.

RAFFENSPERGER: "These men and women, and my office, will continue to follow the law and count every legal vote."

Biden currently holds a narrow lead in Georgia, up by more than 14,000 votes.
