Speculation is high for Comey's book and tour; he is expected to address his unceremonious firing from the bureau by Trump, among other controversial issues from his term as director.

The advertising plan, spearheaded by the Republican National Committee and approved by the White House, will brand the former top law enforcement official "Lyin' Comey" on a new website and in a series of online ads, according to CNN. The phrasing will also be included in talking points sent to Republicans nationwide.

Comey is preparing for a nation-wide publicity tour to follow the release of his memoir.

In response, the Republican plan will provide lawmakers with arguments to counter Comey, including the claim that "attempts to smear the Trump administration are nothing more than retaliation by a disgraced former official," CNN reports.

Digital advertisements will attempt to remind Democrats that they lost faith in Comey during the 2016 presidential race, when he closed and later reopened an official investigation into Democratic presidential candidate Hillary Clinton Hillary Diane Rodham ClintonButtigieg stands in as Pence for Harris's debate practice Senate GOP sees early Supreme Court vote as political booster shot Poll: 51 percent of voters want to abolish the electoral college MORE over her use of a private email server while secretary of State.

"Comey is a liar and a leaker and his misconduct led both Republicans and Democrats to call for his firing," Republican Chairwoman Ronna Romney McDaniel told CNN. "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."

Comey's book, "A Higher Loyalty: Truth, Lies and Leadership," is due out Tuesday and has already become a bestseller.

Since his firing last May, Comey has largely remained silent on the Trump administration but has signaled on Twitter that he would open up in his new book and subsequent tour.

Earlier reports had indicated that the White House would remain quiet and was not planning a countermessage to Comey's book.
