President Donald Trump's former longtime lawyer Michael Cohen pleaded guilty this week to a list of federal crimes as the controversy surrounding him reached a climax.

On Tuesday, Cohen cut a deal with federal prosecutors and pleaded guilty to five counts of tax evasion, one count of making a false statement to a financial institution, and two counts related to campaign-finance violations. Cohen said under oath that Trump directed him to violate campaign-finance laws just before the 2016 presidential election in order to boost his candidacy.

The latter two charges were in connection to payments to the former Playboy model Karen McDougal and the porn actress Stormy Daniels in order to silence their allegations of affairs with Trump.

As Cohen explained that he committed the campaign-finance violations "at the direction of the candidate" and with the "purpose of influencing the election," there were audible gasps in the lower Manhattan courtroom packed with reporters.

The federal prosecutors Cohen struck a deal with said they had evidence corroborating Cohen's admissions, stemming from records obtained from him that included audio tapes, texts, phone records, emails, witnesses with knowledge of the transactions, and records from The National Enquirer.

Later in the week, federal prosecutors probing Cohen granted immunity to Trump Organization CFO Allen Weisselberg, and American Media Inc. CEO David Pecker, who struck the deal with McDougal, The Wall Street Journal reported.

Cohen initially faced the potential of 65 years in prison, but the deal narrowed that sentence down to a much more palatable three to five years, though the judge reserves the right to impose a more severe punishment at a December sentencing.

Lanny Davis, one of Cohen's attorneys, told Business Insider on Wednesday that Cohen feels "pain for his family" that he could go to prison, and relief that the uncertainty is over now that he has a plea deal. Cohen's also not done opening up on what he knows about Trump, Davis said.

"This is the time he knows he's going to jail, and he feels liberated that he can finally speak his mind about his concerns about Donald Trump without a criminal lawyer telling him to 'be quiet' because 'you'll upset the prosecutors,'" he said.

Moving forward, all eyes are on what happens next, particularly for Trump.

"The plea, under oath, establishes that the president was a co-conspirator in the campaign violations to which Cohen pleaded guilty," Philip Allen Lacovara, who served as counsel to the special prosecutors investigating former President Richard Nixon's role in the Watergate scandal, told The New York Times.

Before he resigned from office, a grand jury named Nixon an "unindicted co-conspirator." Lacovara said that is now what Trump "technically" is.

But it appears highly unlikely Trump will be indicted in this instance - at least while he is still in office.
