President Trump has redoubled efforts to end Robert Mueller’s investigation of him and Russia with a three-pronged offensive:

Do everything possible to cast aspersion and doubt on Mueller and his team, such as his continual tweet storms.  Think “witch hunt.”

At the same time intensify distraction tactics featuring a constant fog machine to diminish news coverage of what Mueller has done and is doing (the off-again, on-again Korean summit maneuvering has been helpful with this lately.)

And simultaneously work feverishly to destroy the whole Mueller effort, stop it in its tracks (much of this is happening behind the scenes with Giuliani and Republican leaders in Congress leading the effort.)

From his view, Trump may see reasons to believe that this is working, that things are moving his way.  Recent polls suggest that his approval numbers are now around 44 percent,  up from a low of about 37 percent at the end of last year.  He may well figure that he may not get a better chance of prevailing than right now.
