Sen. Warner: "Don't know how anybody" could juggle Rubio's "two big jobs"

Driving the news: Warner, the top Democrat on the Senate Select Committee on Intelligence, said on CNN's "State of the Union" on Sunday that he doesn't "know how anybody could do these two big jobs."

• The roles of secretary of State and national security adviser, he said, are "frankly very different."
• And on top of those roles, he noted, Rubio is still in charge of "the remnants of what used to be American soft power for 70 years, USAID." He added, "Even for a Marco Rubio ... I think it's too much."
• Warner said he "worked very well with" Rubio for years in the Senate — but he noted he's "disappointed by some of the actions he's taken as secretary in this kind of kowtowing to Trump."

Zoom out: Rep. Jim Himes (D-Conn.), the ranking member on the House Intelligence Committee, said on "Fox News Sunday" that although he would characterize Rubio as an "adult in the room," national security adviser and secretary of state are jobs that "are too big for one person" to hold.

• He continued, "To have both of those jobs, including a bunch of other jobs on the shoulders of Marco Rubio ... these are people who actually need sleep, if we're going to stay out of wars and stuff."

Sen. Tammy Duckworth (D-Ill.) said on CBS News' "Face the Nation" Sunday that there is "no way he [Rubio] can do that and do it well."

• "There's no way he can carry ... that entire load on his own," Duckworth said, citing "incompetence" at the Pentagon under Secretary of Defense Pete Hegseth, who she said should be replaced "as quickly as possible."

The big picture: Rubio now has powers no U.S. official has held since Henry Kissinger, who served as national security adviser and secretary of state under President Nixon, Axios' Marc Caputo reported.

The other side: Rep. Mike Turner (R-Ohio), the former chair of the House Intelligence Committee, pointed to Kissinger when asked by CBS News' Margaret Brennan whether Rubio balancing so many posts was in the nation's security interests on "Face the Nation" Sunday.

• "I think what's also very important here is that Marco Rubio ... from a policy perspective is very strong in this administration," Turner said, contending Rubio's role signals a continuation of "the same policies in the administration."

• Turner added that "hopefully" Rubio will be able to build out a security council team that "represents ... the opportunity to support President Trump and giving him the information and knowledge and the access to information and knowledge that he needs."

Catch up quick: Rubio took over for former national security adviser Mike Waltz, who Trump announced last week was being nominated to be the U.S. Ambassador to the United Nations.

• Waltz's departure from the post came around a month after the news broke that he had accidentally included a journalist in a Signal chat discussing sensitive strike plans.

What we're watching: Warner predicted "a brutal confirmation hearing" for Waltz during Sunday's interview.

• But the person Warner said he thinks "should be gone" is Defense Secretary Pete Hegseth, who has overseen a tumultuous time at the Pentagon marked by several controversies.
• Duckworth echoed that Waltz's hearing will be "brutal" and said she is "not open to voting for him."
• She continued, "he's already demonstrated he's incapable of doing the most basic thing, which is handling classified information."
