The media has been "undermining" him for well over 20 years now... It's because he has a big mouth and does not hesitate to say every stupid thing that comes to his mind.
There are more people against Trump than for Trump. Similarly, there is a lot more money in his opposition than in his support.
They have? Besides Vanity Fair, which is something I have never actually read in whatever doctor's office subscribes to it the media seemed to love Trump when he was a democrat, cameos in all sorts of movies, constant references in pop culture, his appearances on Oprah were all complementary.
he has plenty of pop culture references, and yeah hes done plenty of interviews lol... he was going to run for president with oprah also!
Before becoming president he filed for bankruptcy 6 times, switched political affiliations about 5 times, and threatened lawsuits against thousands of unpaid workers!
The media was making fun of him then too.. though obviously not to the extent of now, considering he is the president.
