Monday's raid on Cohen's office, home and hotel room steps up the pressure on Trump, whose troubles have evolved from political obstacles he could swat away to potentially serious legal problems that could imperil his presidency.
"This is about getting Donald Trump at all costs even if it means stretching the boundaries of exceptions to attorney-client privilege", said former Trump campaign adviser Michael Caputo.
President Trump and his supporters are calling it a biased investigation being run by his opponents, trying to damage him politically.
The raid creates a new legal headache for Trump as he and his attorneys weigh whether to agree to an interview with Mueller's team, which in addition to investigating potential ties between Russian Federation and the Trump campaign is also examining whether the president's actions constitute obstruction of justice. A military strike would mark Trump's second retaliatory strike against Syrian President Bashar Assad's government at a time when Trump is seeking to reduce the US footprint in Syria.

On Monday, when he appeared with his national security team, Mr. Trump, whose motto could be, "The buck stops anywhere but here", angrily blamed everyone he could think of for the "unfairness" of an investigation that has already consumed the first year of his presidency, yet is only now starting to heat up.
Or there could be other non-Stormy-Daniels-related allegations about Cohen's conduct that have not yet surfaced publicly. She said that she thought they would publish her account but that they were really paying to squash her story.
The raid raises a host of questions and highlights the many ways that Cohen, long known as Trump's personal fixer, now could find himself in legal jeopardy.
