Disgraced NBC anchor Brian Williams (pictured) has threatened to make his departure from the channel 'really ugly', it has been reported . He was suspended in February with no pay for six months after it emerged that he repeatedly told a false story about being aboard a military helicopter hit by an RPG over Iraq. A source said to be close to NBC has told The New York Post how Williams 'is saying he’s not going down without a fight and (is) threatening to make it really ugly'. Williams is currently halfway through his six-month suspension from his roles as anchor and managing editor of the Nightly News. He was replaced by Lester Holt, who has kept ratings relatively steady. It is unclear whether NBC will put Williams back in the top slot when the suspension ends. Iraq shame: Williams fell from grace after veterans called him out after he lied about being on board a US military chopper which was hit by a rocket-propelled grenade . Yesterday it was reported that NBC News chief Andrew Lack wanted Williams to resume his role. But this contradicted earlier claims that NBC executives wanted Williams out and were trying to negotiate his resignation. A source told the New York Daily News 'Andy (Lack) believes viewers want him (Williams) back. 'The feeling is that (Williams') problem seems to be more with the media and other reporters than his viewers - if Andy can figure out a way to get him back on the air he will do it.' The source added that Lack 'will not make a decision about Williams' fate until the network's internal probe is complete.' On Tuesday, a report emerged in the Hollywood Reporter that Lack was in fact not convinced that Williams would be able to return. Williams has reportedly been banned from speaking publicly about the investigation, or defending himself against any new claims. He is reported to have signed a deal with the network last year to continue at the network thought to be worth $10million a year. According to the New York Post, NBC News has yet to make any decision's about the newsman's future.
