During first speech post-election on immigration, Vice President-elect Kamala Harris’ told immigration activists that she's focused on working to “right the wrongs of these past four years."

Harris, during pre-taped remarks at the 13th Annual National Immigrant Integration Conference, ticked off a few immigration-related actions the Biden administration hopes to tackle in the first 100 days in office.

“In our first 100 days, we will send an immigration bill to Congress, reinstate DACA, repeal harmful and discriminatory policies like the Muslim ban, and during our administration, we will repeal indiscriminate enforcement policies that tear families apart and make us less safe," Harris said.

The daughter of two immigrants, Harris later noted the sacrifice that immigrants have made during the pandemic as essential workers, vowing to create a “humane immigration system.”

Trump reached out to Pennsylvania State Speaker of the House Brian Cutler last week asking about the legislature possibly overturning the election as part of his ongoing and apparent pressure campaign to have GOP-controlled legislatures flip results in his favor in battleground states he lost.

Mike Straub, a spokesman for Cutler, confirmed to ABC News reporting in The New York Times that Trump asked what options were available to the legislature on the phone call.

“Cutler made it very clear what power the legislature has and does not have," Straub told ABC News, adding he is "not aware of the President explicitly asking to turnover [sic] the election results."

Straub separately told ABC News that he was not present for the conversations between Cutler and the president, but he was briefed.

"The president wanted to know what options were available to the legislature to address those concerns... Speaker Cutler was very clear in explaining what power the legislature has and does not have within our state Constitution," Straub said. "One remedy the Trump campaign is seeking in a court case involves the legislature seating electors -- Speaker Cutler explained the legislature does not have that authority."

Cutler separately signed onto a resolution last week imploring Pennsylvania Republicans in Congress to officially contest the election results in January. While this has happened in the past, including over the election of George W. Bush, it is highly unlikely to overturn the election results.

The Supreme Court may decide Tuesday to take up a challenge by Pennsylvania Republican Rep. Mike Kelly over the constitutionality of mail-in voting, but legal experts have told ABC News that is a long shot. With Tuesday being the constitutionally mandated "safe-harbor" deadline for electors, all legal challenges are meant to be resolved by the end of the day, thus ensuring the correct electors will cast their votes in statehouses on Dec. 14.

Former Cybersecurity and Infrastructure Security Agency Director Chris Krebs has sued Trump campaign lawyer Joe diGenova and Newsmax over comments the Trump campaign lawyer made on the TV network calling for Krebs to be "taken out at dawn and shot."

Krebs’ lawyers say that the Trump campaign and “diGenova, spread, stoked, and instigated unfounded allegations of system-wide voter fraud, abuse, and interference—without proffering any evidence deemed credible by any state or federal court—in a naked and politically motivated effort to undermine public confidence in the election,” according to a complaint filed in Montgomery County, Maryland, court.

Trump fired Krebs last month after he repeatedly rebuked unfounded claims made by Trump and his campaign about widespread voter fraud, which the complaint also hits on.

The lawsuit says Krebs has received death threats through email and on Twitter by, in some cases, “angry Newsmax viewers," with people calling Krebs a traitor who should be hung. These threats were so serious, according to the lawsuit, that Krebs’ 10-year-old child asked, “Daddy’s going to get executed?”

“Seeing the pain and fear in those closest to him has only elevated his own pain and fear,” the lawsuit says. Because of this, Krebs has had to leave his house, retain private security and reported threats to law enforcement.

Krebs is seeking Newsmax to remove the clip as well as monetary damages, with the suit saying that diGenova and the network have a “symbiotic relationship.”

Trump campaign legal adviser Jenna Ellis has informed associates she’s tested positive for coronavirus only days after attending a Christmas party at the White House, igniting panic in the West Wing, multiple sources tell ABC News.

Ellis attended a senior staff Christmas party at the White House on Friday, where she was photographed not wearing a mask.

The news comes just days after it was revealed that Trump’s personal lawyer Rudy Giuliani has been hospitalized after testing positive for COVID-19. Ellis has spent the last month traveling the country with Giuliani working to overturn the 2020 election results in states including Pennsylvania, Michigan and Arizona on behalf of the president. Both have attended hearings without wearing a mask.

Shortly before releasing his press release confirming retired four-star Gen. Lloyd Austin as his pick to lead the Pentagon, The Atlantic magazine published an op-ed penned by Biden op-ed, laying out the reasons behind his choice and noting their history together in the Obama administration.

“Today, I ask Lloyd Austin to once more take on a mission for the United States of America—this time as the secretary-designate of the Department of Defense. I know he will do an outstanding job,” Biden wrote.

Austin, the former commander of U.S. Central Command -- with jurisdiction over military activities in the Middle East -- retired in 2016 after more than 40 years of military service. If confirmed, he would be the first African American to lead the Pentagon.

Biden pointed to Austin’s ”many strengths and his intimate knowledge of the Department of Defense and our government” as factors that made him “the person we need in this moment," saying his experience leading the Iraq drawdown prepares him for coordinating vaccine distribution and connecting with American families.

“And the next secretary of defense will have to make sure that our armed forces reflect and promote the full diversity of our nation. Austin will bring to the job not only his personal experience, but the stories of the countless young people he has mentored. If confirmed, he will ensure that every member of the armed forces is treated with dignity and respect, including Black, Latino, Asian American, Native American, women, and LGBTQ service members," Biden wrote.

Biden also seemed to address the fact that Lloyd’s nomination would require a waiver given his recent military service -- something that some Democrats have already expressed opposition to.

“I respect and believe in the importance of civilian control of our military and in the importance of a strong civil-military working relationship at DoD—as does Austin," he wrote.

"Austin also knows that the secretary of defense has a different set of responsibilities than a general officer and that the civil-military dynamic has been under great stress these past four years," Biden added.

The announcement comes as Biden and Vice President-elect Kamala Harris meet with civil rights leaders who have pushed Biden to name more people of color to senior-level Cabinet positions.
