Classified information, private email servers, and intelligence leaks all helped shape much of the recent debate surrounding US politics.

They changed the outcome of the election, which saw Republican Donald Trump beat his Democratic rival Hillary Clinton. They led to the eventual firing of FBI director James Comey. And now they're engulfing the White House in yet another Russia-linked scandal.

President Donald Trump allegedly revealed highly classified information to top Russian diplomats in a meeting at the White House on 10 May.

According to the Washington Post, the information Trump passed on was given to the US by a partner in an intelligence-sharing arrangement. It is so sensitive that details were not shared with allies and was guarded within the government, officials said.

Republicans have tried to downplay the incident, and the White House flat out denies that any classified material was passed on. But it was less than a year ago that they were up in arms at the way Clinton had exposed herself by using a private email server while handling classified data.

Trump himself tweeted out that Clinton wasn't "fit" over her handling of the whole saga, saying: "Crooked Hillary Clinton and her team "were extremely careless in their handling of very sensitive, highly classified information." Not fit!"

The FBI investigation recommended the Justice Department not bring charges against Clinton for her handling of classified data. Still, Comey said Clinton and her staff were "extremely careless" in using a private email server.

A number of high-profile members of Trump's team and senior Republicans were also critical of Clinton at the time.

Republican house speaker Paul Ryan said: "It's simple: Individuals who are 'extremely careless' w/ classified info should be denied further access to it."

Trump's now chief of staff, Reince Priebus, said at the time: "Those who mishandled classified info have had their sec clearances revoked, lost their jobs, faced fines, & even been sent to prison."

Texas senator Ted Cruz was equally critical of Clinton, but just as silent about Trump's alleged leak, saying: "It's abundantly clear her handling of classified info on a private email server was grossly negligent, as the FBI admitted this summer."

Even Trump's current press secretary, Sean Spicer, criticised Clinton about the incident, but reports of rows inside the West Wing last night suggest they struggled to handle the episode themselves.

The list of Republicans who chastised Hillary Clinton goes on. But the list of Republicans who have criticised Trump is rather smaller.
