The Moreland Commission was an anti-corruption group, set up by Andrew Cuomo in July 2013, only to shut it down in 2014.
According to the Huffington Post, the commission was investigating political firms hired by Cuomo, and the major donors to his campaign for governor.
Bharara was not on the commission, but he was part of the team which investigated why Moreland had been shut down.
According to Politico, Bharara concluded that there was not enough proof of a federal crime, such as using your power as governor to close down an anti-corruption group that's looking into you.
Absent any additional proof that may develop, there is insufficient evidence to prove a federal crime.
However, Bharara's office did state they would take up the work that Moreland had begun, given that the Moreland commission had been in the middle of investigations when it was prematurely abolished.
Legum's logical leap comes at point 4, with the implication that much like the Moreland Commission being shut down by Cuomo, who it was investigating, Bharara was fired as he came close to investigating Donald Trump.
Last week, the president claimed that former president Obama had ordered his Manhattan headquarters, Trump Tower, be bugged by the intelligence agencies.
Wiretapping by law enforcement as Trump claims, would require authorisation. This could include his being investigated by the justice department.
Asked whether or not the President was under investigation, the department of justice responded with 'no comment'.
