Gov. Andrew Cuomo said to reporters on Thursday that if President Donald Trump pardons his former personal lawyer Michael Cohen, it could be seen as an “impeachable offense” and possibly an obstruction of justice.

Cuomo said there’s speculation that Trump could pardon Cohen to escape testimony from Cohen connecting him to crimes that Cohen pleaded guilty to earlier this week. Cohen implicated Trump in hush-money payments to two women before the 2016 election while pleading guilty to his involvement in the scheme.
