CNN’s Alisyn Camerota led a conversation on Wednesday about the possibility of replacing President Joe Biden on the Democratic ticket following his poor debate showing, and commentator Ana Navarro pointed out that it’s not just a difficult process, there’s a time limit as well.

Navarro, also a co-host of ABC’s The View, is an outspoken supporter of Biden but recognized that questions needed to be asked concerning his health. Addressing the upcoming sit-down interview Biden has planned with ABC’s George Stephanopoulos, Navarro pitched the first question that needed an answer:

I think the key question that Stephanopoulos I hope asks, and that I think a lot of us want answered, is “Do you have, was this a one-off or do you have a condition? Do you have a medical diagnosis that the American people should know about?” Or “How do you explain what happened last Thursday?” Give us that.

But Navarro also drove the point home that if Biden and the Democratic party were going to make a decision about changing the ticket — or not changing the ticket — it had to happen fast:

I’ll tell you what the other data point will be: the clock. The calendar. Right? The Republican convention’s in two weeks. The Democratic convention is in six weeks. So the time is running out to make these changes. There’s a lot of procedural, legal, FEC issues that have to be sorted out if you’re talking about changing a candidate. This is not like changing a boyfriend in high school. This entails an enormous amount of things that need to get done, and I don’t think people are thinking about that. There’s ballots being printed, there’s primaries that have happened, different states have different regulations. So there’s a time that’s going to come when making this change… You know, people think there’s going to be a white knight that comes out of the sky. Well, they’re running out of time for that white knight to appear.
