Major moments from Michael Cohen’s long history with Trump

Michael Cohen, President Donald Trump’s former lawyer, will be sentenced Wednesday after he pleaded guilty to tax evasion and campaign contribution violations, as well as lying to Congress about negotiations to build a Trump Tower in Moscow in the runup to the 2016 presidential election.

The sentencing will culminate a swift fall from grace for Cohen, who spent more than a decade working for Trump and for his organization before getting caught up in special counsel Robert Mueller’s investigation into Russia meddling in the 2016 presidential election. Cohen is now cooperating with the special counsel’s probe, and has also cooperated with federal prosecutors in New York, where he is being sentenced Wednesday by a federal judge.

Ahead of the sentencing, here’s a timeline to help keep track of the federal probe in New York and Cohen’s involvement in the Russia investigation. Some of these entries also live in PBS NewsHour Correspondent Lisa Desjardins’ interactive, frequently updated giant Russia timeline. Check out the full timeline here.
