Where are you getting this information from? In the article that I read Jill’s ex claimed that Joe starting getting close to Jill (and a little too close according to some acquaintances) two years earlier than Jill claims.
Although this article was clearly biased against Biden as it mentions how he and his brother threatened the ex to let Jill have the entire house or they’re going to send the DOJ after him (which they ultimately ended up doing) so I don’t know which is accurate one way or the other.
You may also want to read up about how Biden destroyed the life of the truck driver after his late wife accidentally drive into his path. Biden claimed that he was drinking- which was a lie. She ran a stop sign and he didn’t.
By the way- President Trumps moral behavior isn’t in question so I’m not sure why you’re bringing it up. The issue is with people who say that they’re not voting for President Trump because of his immortality but would have voted for Biden if he wasn’t forced out.
