The greatest threat to Trump and his presidency, say administration officials and outside advisers, comes from his own conduct and obsessive behavior after he took office. While congressional and FBI investigations may prove Trump or his team broke laws before he took office, his advisers say they’re more worried that the things he’s done since the inauguration may have left him exposed to obstruction of justice or other charges.

Trump, for months, has bristled almost daily about the ongoing probes. He has sometimes, without prompting, injected. “I’m not under investigation” into conversations with associates and allies. He has watched hours of TV coverage every day — sometimes even storing morning news shows on his TiVo to watch in the evening — and complained nonstop…

Two people close to Trump note that his is an obsessive personality — whether about businessmen who wronged him over the years, his years-long and fruitless quest to prove President Barack Obama wasn’t born in the United States, to reporters who have written negative stories about him. One transition official said Trump lashed out at reporters over old stories within a day of winning the election in November.
