Biden will hold a news conference Tuesday to defend himself against accusations of being soft on immigration, his first such press conference since the nomination of his vice president was announced.
The vice president’s comments in the New York Times interview came days after he spoke with reporters in Miami and said he was confident in his nominee for secretary of state.
Biden said he wanted to “put out there that I believe the nominee will be the most qualified person to take on the challenges facing our country.”
“I am confident that he will do the job,” he added.
The vice presidencies nominee is widely expected to win support from Democrats.
It is the most high-profile choice for a top Cabinet position since the appointment of former New York Gov.
Michael Bloomberg in 2002.
“Biden is someone who has the experience, the knowledge and the background to do the important jobs we have to do to make sure that America is secure, that America’s interests are protected, and that we’re able to provide for our families and our children,” said Rep. John Lewis, D-Ga., a senior member of the Congressional Black Caucus.
Cory Booker of New Jersey and Joe Manchin of West Virginia are expected to announce the next nominee later Tuesday.
While some of the party’s most prominent voices have expressed reservations about his nomination, many in Congress and in some Democratic constituencies support his nomination.
In a statement Tuesday, House Minority Leader Nancy Pelosi, D.-Calif., called Biden’s comments “very important” and “deeply troubling” and said that he has the “character and the temperament to lead this country.”
She said the nomination “will give our nation’s next secretary of defense the leadership and experience necessary to secure the border, secure our nation from terrorist attacks and keep our troops safe and focused on the important work of protecting our homeland.”
