The "Lyin' Comey" website also portrays him as a politically motivated Washington insider.
The Republican National Committee launched the lyincomey.com website on Thursday, which highlights previous criticisms of Comey by Democrats and urges visitors to "check the facts" before believing any claims his "grandstanding book" will make.
Comey apparently compares Trump to a mob boss in a new ABC News interview that is set to air this weekend. The network has already released a teaser of one exchange, in which Stephanopoulos suggests that Comey likened Trump to a "mob boss". Two months before he would be named White House chief of staff, Kelly told Comey that he was "sick" over the firing, Comey writes in his new book A Higher Loyalty, according to a report in the Daily Beast.
Talking points prepared by the RNC and obtained by ABC News will be distributed to surrogates and allies of the president and are aimed at attacking what are called Comey's "misstatements and misconduct", contradictions and credibility.
Trump would regret abandoning nuclear deal, warns Iran
Under the 2015 agreement, Iran promised to scale back its nuclear enrichment and give up its pursuit of nuclear weapons. United States sanctions will resume unless Trump issues new "waivers" to suspend them on May 12.
"Attempts to smear the Trump administration are nothing more than retaliation by a disgraced former official". The homepage features a cycle of quotes from prominent Democrats questioning Comey's tenure.
With the Mueller probe escalating - including the Federal Bureau of Investigation raid this week of Trump's personal lawyer's home and office in Manhattan - Comey's media appearances could pose a major public relations challenge for the White House.
"If Comey wants the spotlight back on him, we'll make sure the American people understand why he has no one but himself to blame for his complete lack of credibility", she said.
At the bottom of the homepage, the RNC trumpets "Obstruction?" noting that Comey "may" use his book tour to "push the phony narrative" that Trump obstructed the Russian Federation investigation. That contradicted a remark he made earlier when testifying that the President did not ask him to stop an investigation for political reasons.
Trump has defended himself, saying he simply fired Comey "very simply" because "he wasn't doing a good job".
