Rudy Giuliani tells ABC News he will not be part of President Donald Trump's legal team for the upcoming Senate impeachment trial.

“Because I gave an earlier speech [at the January 6 Trump rally before the Capitol riot],” Giuliani told ABC News Sunday night, “I am a witness and therefore unable to participate in court or Senate chamber.”

Trump was impeached by the House for the second time last week following the siege on the Capitol by a pro-Trump mob.

The Delaware Humane Association hosted a virtual party with over 10,000 people to celebrate the first shelter dog moving into the White House.

While Champ and Major won't put their paws in the White House until Wednesday, the association held the fundraiser Sunday to celebrate the history being made: Major was adopted by Biden in March 2018.

"It means everything to us because it shines a light on the work we do," Delaware Humane Association's executive director Patrick Carroll said Sunday during the virtual party. "It shows that shelters are a wonderful place to adopt."

The shelter showed off photos of Major during his stay there in 2018 along with video of him and the president-elect. It also revealed dog "secretaries" which were dogs from its shelter that were selected by fans.

The Delaware Humane Association raised over $100,000, according to its host.

Biden's two German shepherds will also be the first dogs to live in the White House in four years, though Champ is no stranger to Washington. The Biden family brought the dog into their home in 2008 and he resided with them during his two terms as vice president.

The National Security Agency confirmed to ABC News that Michael Ellis has been named to be the agency’s new general counsel.

Ellis, who is considered to be a Trump loyalist, was pre-selected for the job, but his placement was slow-rolled by NSA Director Paul M. Nakasone.

Acting Defense Secretary Chris Miller demanded the NSA to put him in the career civil service job by 6 p.m. Saturday night, according to a source.

"Mr. Ellis accepted his final job offer yesterday afternoon. NSA is moving forward with his employment," an NSA spokesperson said in a statement provided to ABC News.

The Washington Post first reported the installation.

The NSA’s general counsel is a career civil service position and not an appointee position. Anyone in that post would continue on regardless of a change in administrations. They could only be removed under the same guidelines in place for other civil servants. There is a probationary period and tenure policy in place.

Virginia Rep. Abigail Spanberger called it “a point of sadness” after she joined her fellow Democrats and some Republicans Wednesday to vote to impeach Trump.

“Impeachment is necessary at this point in time because we have to make a clear statement that the incitement of an insurrection by a sitting U.S. president is absolutely unacceptable,” she told ABC's “Nightline.”

She acknowledged how close the president is to the end of his term, but said it’s still necessary to impeach Trump because it’s an “issue of accountability.”

“It’s an issue of law and order. It is an issue of ensuring that every person who holds this office in the future recognizes and knows and understands that in the United States of America, under no circumstances do we accept that the president … would incite a violent mob to insurrection for the purpose of holding onto power. It’s unacceptable, and generations into the future need to know that we believe that to be the case.”

The Democratic congresswoman has served Virginia’s 7th Congressional District since 2019. She said that the riot at the U.S. Capitol building last week during a joint session of Congress was “unimaginable.”

Spanberger also said it’s “ridiculous” to compare the Capitol insurgence to last year’s Black Lives Matter protests like some House Republicans did Wednesday.

“I have categorically denounced violence in all its forms, in any circumstance,” she said. “But this wasn’t violence. This was a domestic terrorist attack perpetrated by insurrectionists who lowered the flag of the United States and raised a flag with one man’s name on it.”

“It couldn’t be more different,” she added, “and false equivalencies are deeply saddening and disheartening, particularly for those of us who have sworn an oath to uphold the Constitution from all enemies, foreign and domestic.”
