Trump fired Comey in May 2017 amid the FBI's investigation into Russian interference in the 2016 presidential election.
The book, "A Higher Loyalty: Truth, Lies and Leadership", was released at midnight US eastern time, but that did not stop late night customers queuing up to buy a copy.
In March, the Trump administration expelled 60 Russian diplomats and suspected spies from the United States after Britain accused Russia of attacking a former spy, living in Britain, with a military-grade nerve agent. Several of the episodes he describes in detail, including a private conversation about former White House national security adviser Michael Flynn, are central to special counsel Robert Mueller's investigation and his recollections are presumably valuable for prosecutors examining whether the president's actions constitute obstruction of justice.
Comey's remarks, coupled with the release of his forthcoming book, offer his version of events surrounding his firing and the investigations into Russian election meddling and Clinton's email practices.
Despite support for penalizing Russia, 52 percent of adults say Trump should invite Vladimir Putin to the White House in an effort to improve U.S. -Russia relations, while 42 percent say Trump should not do so, because it would grant Putin legitimacy. But he said that in Trump's case, he could not discount the possibility that the president had been compromised.
"Comey drafted the Crooked Hillary exoneration long before he talked to her (lied in Congress to Senator G), then based his decisions on her poll numbers". It's also about how he views the conduct of the highest officeholder in the country.
Attorney General Jeff Sessions fired McCabe last month, two days before his retirement was to take effect.
"A person who sees moral equivalence in Charlottesville, who talks about and treats women like they're pieces of meat, who lies constantly about matters big and small and insists the American people believe it - that person's not fit to be president of the United States, on moral grounds", Comey said. It doesn't really matter who knew, or didn't know, since all the blame has been placed on Trump and the Russians. After Clinton's loss, many Democrats blamed Comey, and Clinton herself has said it hurt her election prospects. "Disgruntled, he, McCabe, and the others, committed many crimes!" he tweeted Monday. "People in this country need to stand up and go to the voting booth and vote their values". "Donald Trump's presidency threatens much of what is good in this nation", Comey writes. And that's as it should be, and it's always been that way. "That's our foundation. And so impeachment, in a way, would short circuit that".
