Senator John Kennedy and the Daubert standard

There is a posting of a video related to questioning of (now withdrawn) judicial candidate Matthew Petersen.

One of the exchanges:



Senator KENNEDY: As a trial judge, you’re obviously going to have witnesses. Can you tell me what the Daubert standard is?

PETERSEN: Sen. Kennedy, I don’t have that readily at my disposal but I would be happy to take a closer look at that. That is not something I’ve had to contend with.



One notes that Daubert relates only to the the admissibility of testimony of an expert witness, and is not about "witnesses" generally.

See for example, LBE, Frye after Daubert: The Role of Scientists in
Admissibility Issues As Seen through Analysis of
the DNA Profiling Cases

The University of Chicago Law School Roundtable: Vol. 1 : Iss. 1 , Article 19.
