NBC News correspondent Tom Costello worried on Tuesday that no one would be able to “police” former Fox News host Tucker Carlson if his show aired on Twitter.

Costello brought in ousted CNN anchor — and regular Fox News critic — Brian Stelter to discuss the situation, responding to Carlson’s announcement that he planned to bring a similar version of his popular show back to Twitter in the near future.

NBC’s reaction to Tucker Carlson’s Twitter show announcement: “Will anybody be able to police what Carlson says or is this the point? It’s just a free for all?”

“Twitter was already under fire for misinformation, disinformation, all-out lies, anti-Semitism, racism before Elon Musk took over and now it’s gotten kind of crazy, right? Seemingly unmoored, if you will,” Costello began.

Pivoting to the direct question, Costello asked, “Will anybody be able to police what Carlson says? Or is this the point? It’s just a free-for-all?”

Stelter quickly agreed that having no rules appeared to be the point, saying, “It is a free-for-all, it’s what Elon Musk wants to provide. This move by Tucker may cement the idea of Twitter as a Right-wing website, and we see some users trying to go off to other sites instead.”

In his Tuesday announcement, Carlson said that he wanted to take his show to Twitter because he believed it to be one of the few places where free speech was truly allowed — and even valued — and because Twitter as a platform did not take political sides.

Twitter owner Elon Musk revealed after Carlson’s announcement that he had not been a part of any signed deal with the ousted Fox News host — but in the hours that followed, he reached out to former CNN anchor Don Lemon (who was fired by his own network the same day Fox announced Carlson’s departure) and suggested he come to Twitter as well.

“Have you considered doing your show on this platform? Maybe worth a try. Audience is much bigger,” Musk tweeted in response to Lemon’s April 24 tweet announcing his termination.

Sen. Dianne Feinstein (D-CA) returned to the Senate on Wednesday in a wheelchair, ending the lawmaker’s months-long absence as she recovered from shingles.

Video shows Senate Majority Leader Chuck Schumer (D-NY) walking alongside Feinstein as she was being wheeled into the Senate chamber for a vote.

Liz Kreutz, a reporter for ABC7 San Francisco, tweeted that Feinstein’s office said the senator is “experiencing vision/balance impairments & at times will need to use a wheelchair to travel around the Capitol.”

It's official: @SenFeinstein is back on Capitol Hill. Here is the moment she voted on the Senate floor. She was escorted in by @SenSchumer

A statement released by Feinstein explained her situation.

“Even though I’ve made significant progress and was able to return to Washington, I’m still experiencing some side effects from the shingles virus,” Feinstein said. “My doctors have advised me to work a lighter schedule as I return to the Senate. I’m hopeful those issues will subside as I continue to recover.”

At the age of 89, Feinstein is the Senate’s oldest member — and in recent years, some colleagues had begun to raise concerns about her mental fitness. Feinstein announced in February she would not seek re-election in 2024. Three prominent House Democrats — Reps. Adam Schiff, Katie Porter, and Barbara Lee — have announced campaigns to replace Feinstein in the Senate.

In early March, Feinstein announced she had been diagnosed with shingles and has been recovering ever since. Because Feinstein is a member of the Senate Judiciary Committee, her absence resulted in a 10-10 split along party lines that rendered the panel unable to advance some of President Joe Biden’s nominees to federal courts around the nation.

In recent weeks, some Democrats, including Reps. Alexandria Ocasio-Cortez (D-NY) and Ro Khanna (D-CA), began to call for Feinstein to resign, and Republicans kept the pressure going by blocking a bid to replace Feinstein on the Judiciary Committee.

“I have returned to Washington and am prepared to resume my duties in the Senate. I’m grateful for all the well-wishes over the past couple of months and for the excellent care that I received from my medical team in San Francisco,” Feinstein said in her statement on Wednesday.

“The Senate faces many important issues, but the most pressing is to ensure our government doesn’t default on its financial obligations,” Feinstein added. “I also look forward to resuming my work on the Judiciary Committee considering the president’s nominees.”
