"That's a question that has to be asked to Secretary Clinton," Becerra said.

Becerra, a tireless campaigner for Clinton, continued to defend the former secretary of State amid controversies regarding the investigation into her private email server.

But Becerra, the chairman of the House Democratic Caucus, said Clinton had a great group of people to choose from to be her running mate.

"I have full faith and total confidence that she's going to make a great decision."

"And we'll see," he added.

Sen. Cory Booker (D-N.J.) declined on Sunday to directly answer a question about whether or not he is being vetted by the Clinton campaign, something he has flatly denied in the past.

"I'm referring questions ... to the woman that's going to have to make this decision," Booker said on CNN's "State of the Union."

"That's not a no?" asked host Brianna Keilar.

"That is exactly what it is. If you have a question like that, please direct it to the Clinton campaign," Booker said.

Booker strongly defended the presumptive Democratic nominee, saying it's not possible she will by indicted in the FBI's investigation into her personal email server.

"That's just not going to happen," Booker said.

The FBI interviewed Clinton for three and a half hours on Saturday, but Booker said the interview was routine. He said he expects the investigation will be closing up soon.

"I think there won't be an indictment. And I think that means she did what many secretaries of State have done in the past," he said.

"I mean, she released more emails and more pages of emails and more records than any of her predecessors of secretary of State, even before she was actually running for president. I think that speaks to her integrity."

Similarly, Labor Secretary Tom Perez, also reported to be under consideration for Clinton’s VP, slammed Trump on foreign policy, drawing contrasts between the real estate mogul and Clinton.

“Well, I haven't run a Ms. Universe pageant, and I don't own any golf courses in Scotland, Chuck, so I don't have what Donald Trump has, and I'm very sorry about that,” Perez said on NBC’s “Meet the Press” with Chuck Todd when asked to describe his foreign policy philosophy.

“It's all about judgment. And Donald Trump is such a volatile individual. And what I have seen working with Secretary Clinton is that she is a steady hand,” he said.

“We are in the midst of a very challenging set of circumstances around the world. And you need someone with a steady hand. And Secretary Clinton, with her experience, with her steady hand, and with her sound judgment. Judgment is what it's all about. And I think she has exercised sound judgment throughout,” he said.

He added Trump was a "train wreck" for trade, the minimum wage, immigration and "American values."

Perez said he's excited to support Clinton because she "understands that when you attack Muslims, when you attack immigrants, you're attacking the core of American values."
