The publisher of former FBI Director James Comey’s memoir announced Wednesday it will move up the release date for his upcoming book.

Flatiron Books said in a statement that there is a pressing demand for Comey’s voice in the “urgent conversation” about the FBI. The statement comes as President Trump and Republicans continue to accuse the bureau of political bias as it conducts an investigation into Russian meddling in the 2016 election. {mosads}

Comey’s book, “A Higher Loyalty: Truth, Lies, and Leadership,” was set to be released in May 2018. The book will now be released on April 17.

Republicans in Congress have amassed evidence they say points to efforts by the bureau to undermine the Trump presidency through the Russia probe, which is looking for possible ties between the Trump campaign and Russia. Trump has also accused Justice Department leadership of bias in recent days.

Special counsel Robert Mueller, the federal investigator heading the probe, is looking for evidence that Trump obstructed justice by firing Comey, who led the investigation before Mueller.

The Amazon description of “A Higher Loyalty” says that Comey’s book will include his experiences from the “highest-stakes situations” of his career in the George W. Bush and Obama administrations.

“His journey provides an unprecedented entry into the corridors of power, and a remarkable lesson in what makes an effective leader,” the description reads.
