The eyes of the world will once again fall on Vancouver.

That's because protesters are planning to gather outside the Trump International Hotel and Tower in Vancouver on February 28 to coincide with the visit of two of Donald Trump's sons.

Donald Trump Jr. and Eric Trump's upcoming trip for the hotel's opening even made it into last night's monologue on the Late Show With Stephen Colbert.

Colbert pointed out that the Trump family charged U.S. taxpayers $11.3 million in travel costs in one month.

The late-night comedian noted that business trips by members of the Trump Organization are among the biggest expenses. When Eric Trump went to Uruguay, for example, it cost taxpayers $97,830 in hotel bills, according to the Washington Post.

"Now, it was $10,000 for the Secret Service and $87,000 for a bottle of Voss water from the mini bar," Colbert quipped.

Colbert also cited a Slate article reporting that U.S. taxpayers will also be subsidizing the brothers' trip to Vancouver.

"It is never a good sign when even the president's sons are looking at real estate in Canada," Colbert said to loud applause.

Colbert neglected to mention that the Trumps' visit to Vancouver will likely cost Canadian taxpayers a fair chunk of change in policing costs.

If the Secret Service accompanies the Trump sons to Vancouver, there's also a question whether these U.S. agents will be armed.

Armed foreign bodyguards created an uproar before

A controversy over armed foreign bodyguards arose following the the Asia-Pacific Economic Co-operation summit in Vancouver in 1997.

That's when Indonesian dictator Suharto brought his armed security detail to the city.

Then Globe and Mail reporter Jeff Sallot cited documents the following year revealing that the Mounties permitted Suharto's bodyguards "to carry concealed weapons during the summit".

However, Suharto's agents were told that "shooting demonstrators 'would not be tolerated'."

"The Indonesians also wanted the police to clamp down on Canadian news media that might be critical of Suharto," the newspaper reported. "The Mounties said they couldn't control the press."

The Inter Press Service, a global news agency, reported that Canadian officials feared that Suharto might boycott the event, so they promised that he would not see protesters.

The article by Canadian journalist Mark Bourrie cited documents contradicting parts of Sallot's article, with Bourrie reporting that the Mounties actually "opposed the decision to allow armed foreign guards into Canada" for the APEC summit.

"They apparently even chased them through Vancouver parks, hotel stairwells, and a university campus," Bourrie wrote. "The documents show that the Canadians were prepared to shoot the Suharto agents, going so far as to surreptitiously slip a heavily-armed emergency response unit into Suharto’s motorcade. At least five of Suharto’s guards were arrested at gunpoint during the summit and expelled from Canada. Several more had their passports seized after they asked Canadian officials if they could shoot demonstrators if their protesters upset the Indonesian leader."

At the time, Canadian companies had extensive investments in Indonesia as human rights groups were condemning Suharto's authoritarian rule.
