Now that the Fake News media is being hammered for trying to use the hoax bombs for political purposes, POTUS should hammer on them about promoting the caravan.
He should point out how dangerous the trip is, how the border will be closed, how there is illness and suffering and those infections are spread in the groups to each other and the children.
Talk about the cartels that operate along the border, them kidnapping and abusing migrants, how women and children are disappeared, etc. And then bash the fake news media for promoting the trek and putting all these innocent people at risk with their lies to support a political agenda. That the fake news and dems don't care about the people, if they did, they would tell them not to come and to stay home and stay safe.
Bash the fake news for putting desperate people, especially the children, into a terrible terrible situation with all these false promises.
