ten minute video and an article where they evidently don't know they're being 'filmed' and they admit lying is their way to avoid being held to a particular 'value';

(Tennessee) Project Veritas Action Fund has released a second undercover video from campaigns during this 2018 election season. This report exposes Tennessee staffers from Phil Bredesen’s U.S. Senate campaign revealing his willingness to court moderate voters through deceit. This was especially evidenced by Bredesen’s recent statement suggesting he would, if he was already in the Senate, vote to confirm now Supreme Court Justice Brett Kavanaugh.
James O’Keefe, founder and president of Project Veritas Action, said this report should represent a red flag for all Tennessee voters:

Phil Bredesen and his campaign have been shown to lie to Tennesseans, saying one thing to persuade voters on the campaign trail but clearly planning to do something entirely different should he get into office. 

Lying to Persuade Moderate Voters
Maria Amalla and Will Stewart, staffers in Bredesen’s campaign, both say on hidden camera that if he were in the Senate, Bredesen would not actually have voted to confirm then-Judge Brett Kavanaugh. They explained that the statement Bredesen issued in support of Kavanaugh was a political ploy to gain the support of moderate voters in Tennessee.
