POTUS needs to encourage viewers to SEARCH FOR THEMSELVES on the search engine of their choosing.
This is one area where POTUS can make a big impact- live on air TELLING viewers to pull up a search engine in real time and search for key terms leading to the plethora of EVIDENCE against Hunter/Joe.
When he just makes the claim, normies just think "eh, Trump's lying". But if he tells them live on the air to search for specific things, then they will see them on their own with their own eyes.
