Giuliani won’t be on Trump impeachment team

Vice President Mike Pence addressed the incoming Biden-Harris administration during a speech at the Lemoore Naval Air Station in Fresno, California, Saturday.

"As a new American administration prepares to take office, we do well to remember as Americans that the price of freedom is eternal vigilance, and that a free and open Indo-Pacific is essential to our prosperity, our security, and the vitality of freedom in the world," Pence said during his remarks to sailors. 

Pence urged the incoming administration to "stay the course" in the region.

"Do what we’ve done," he said. "Stand up to Chinese aggression and trade abuses. Stand strong for a free and open Indo-Pacific and put America and our freedom-loving allies first."

The Trump administration identified China as the greatest long-term threat to the U.S. The Asian nation has shown more assertiveness in the region, including expanding its military presence in the South China Sea. 

Biden has said he may keep some of Trump's tariffs in place and expand human rights sanctions, but he's also expected to take a different tact than Trump's "America First" strategy.

Incoming White House Chief of Staff Ron Klain gave an overview of the first 10 days of the Biden-Harris administration in a memo to senior staff Saturday shared with reporters.

"President-elect Biden is assuming the presidency in a moment of profound crisis for our nation. We face four overlapping and compounding crises: the COVID-19 crisis, the resulting economic crisis, the climate crisis, and a racial equity crisis. All of these crises demand urgent action," Klain wrote. "In his first 10 days in office, President-elect Biden will take decisive action to address these four crises, prevent other urgent and irreversible harms, and restore America’s place in the world." 

The schedule is not comprehensive, Klain noted, but includes:

Jan. 20: Biden plans to ask the Department of Education to extend the pause on student loan payments and interest for Americans with federal student loans, rejoin the Paris Agreement, reverse the "Muslim Ban" (one of Trump's earliest executive orders upon taking office) and issue a mask mandate for federal property and inter-state travel. He will also "take action to extend nationwide restrictions on evictions and foreclosures and provide more than 25 million Americans greater stability."

Jan. 21: Biden plans to sign several executive actions "to move aggressively to change the course of the COVID-19 crisis and safely re-open schools and businesses, including by taking action to mitigate spread through expanding testing, protecting workers, and establishing clear public health standards." 

Jan. 22: The president-elect will direct his Cabinet agencies "to take immediate action to deliver economic relief to working families" impacted by the pandemic. 

Jan. 25-Feb. 1: Among other executive actions, memoranda and Cabinet directives, Biden plans to sign additional executive actions to address the climate crisis, as well as take steps to "strengthen Buy American provisions," reform the criminal justice system, expand health care access and "start the difficult but critical work of reuniting families separated at the border."

"Full achievement of the Biden-Harris Administration’s policy objectives requires not just the executive actions the president-elect has promised to take, but also robust Congressional action," Klain wrote.

House Democrats have opened an investigation into what law enforcement and the intelligence community knew about threats to the Capitol ahead of the Jan. 6 siege.

The investigation from the House Intelligence, Oversight, Homeland Security and Judiciary committees will also examine whether anyone with security clearances -- current or former National Security, Defense, Justice or Homeland Security officials -- participated in the riot.

The investigation will also examine the federal law enforcement response in the aftermath of the attack.

"The Committees will conduct robust oversight to understand what warning signs may have been missed, determine whether there were systemic failures, and consider how to best address countering domestic violent extremism, including remedying any gaps in legislation or policy," committee members wrote in a letter to the FBI, DHS and Office of the Director of National Intelligence.  

"This still-emerging story is one of astounding bravery by some U.S. Capitol Police and other officers; of staggering treachery by violent criminals; and of apparent and high-level failures -- in particular, with respect to intelligence and security preparedness," the letter later stated.

Democrats plan to request documents and briefings from administration officials as part of the investigation -- just one of several looking into the Capitol attack.

When Vice President-elect Kamala Harris takes the oath of office at Wednesday's inauguration, the magnitude of her historic election will be marked not only in her remarks but in the details.

The vice president-elect will be sworn in by Justice Sonia Sotomayor, another historic female first. Sotomayor is the first Latina Supreme Court Justice.

Harris, according to a source with knowledge, told ABC News that the vice president-elect was inspired by Justice Sotomayor's background. The pair both previously served as former prosecutors -- Harris in California, Sotomayor in New York.

During her victory speech, Harris weaved in an adage from her mother, Shymala Gopalan Harris, who often told her she would be the first to do many things, but urged her to open doors for others.

"While I may be the first woman in this office, I will not be the last," said Harris.
