Continuity mistake: After the scene where the first Umbrella Corp. employee gets eaten, the rest are discussing what just occurred. All their clothes appear to be dry. They just scrambled to get out of the river and should all be soaking wet.
Continuity mistake: When Cole is lost in that underground cave, first he has a silver torch with a handle, and then when he meets Tran he has a thick chunky one, then it changes back to the silver one.
Continuity mistake: The woman who falls off the boat is pulled underwater by the crocodile. When she is rescued, there are no signs of bite marks or any other trauma.
Answer: I interpreted it as "I can't support this claim the chemical will extend cell life" because she already said it was impossible. However, the way the line sounded when delivered off screen makes it seem like it was dubbed over different dialog. So someone may not have like what was initially said and had this in as a foreshadowing of her objections later in the film, or it was just a throw away line.

Nothing was stopping her from saying that before they left the United States so that is awful writing. She had no valid reason to think or expect that saying "I can't support this" would change the President and other persons minds after they saw a great presentation with images along with science research to substantiate the claim that the blood orchid flower could renew human youth like a fountain of youth. I assume by objections you mean she didn't want to continue to go through with the expedition after Ben was killed by a giant anaconda, also she gave some answer about evidence not being valid.
