You can impeach a witness if you can cast enough doubt on their credibility even if you can't prove perjury. Basically, your mom will not be allowed to testify in your defense that you were totally with her the whole night that one dude was killed. Having a historical record of pretty strong disdain for Trump could be used to make the argument that she would lie to incriminate him.

That's not a question of whether her testimony is admissible, though. That's just going to be a subject for cross examination and the ultimate credibility determination.

Edit: which, if not those previous statements, she almost certainly has a veritable closet of skeletons to impeach her testimony with.
