NEW YORK (NYTIMES) - It started with an unexpected call last week from Lynne Patton, a long-time Trump associate who oversees federal housing programmes in New York.

Ms Patton told a leader of a tenants' group at the New York City Housing Authority, the nation's largest, that she was interested in speaking with residents about conditions in the authority's buildings, which have long been in poor repair.

Four tenants soon assembled in front of a video camera and were interviewed for more than four hours by Ms Patton. They were never told that their interviews would be edited into a two-minute video clip that would air on Thursday (Aug 27) night at the Republican National Convention and be used to bash Mayor Bill de Blasio, three of the tenants said in interviews on Friday.

"I am not a Trump supporter," said one of the tenants, Ms Claudia Perez. "I am not a supporter of his racist policies on immigration. I am a first-generation Honduran. It was my people he was sending back."

The episode represents another stark example of how President Donald Trump has deployed government resources to further his political ambitions.

Ms Patton is head of the New York office of the Department of Housing and Urban Development and under the Hatch Act, is barred from using her government position to engage in political activities.

Throughout the convention, Mr Trump shattered the traditional boundaries between government and politics, and the video was aired on a night when the campaign took over the South Lawn of the White House, the first time that a major political convention has occurred there.

The public housing clip was the second instance of the Trump campaign's misleading participants in an event involving the federal government that was filmed for the Republican National Convention.

On Tuesday, the convention showed a video of five new American citizens being sworn in at a naturalisation ceremony by Mr Trump. Some of the five said they did not know that they were being filmed for a political event.

Three of the four tenants in the public housing video were interviewed on Friday by The New York Times. All three said they opposed Mr Trump and were misled about the purpose of the video.

In the video, the tenants raised concerns about conditions in the housing authority's buildings, attacking Mr de Blasio's housing record.

Ms Perez, one of the tenants, said in an interview on Friday afternoon that she stood by her criticism of the authority but was furious about being tricked into appearing in the video.

She said she had been called last week by another tenant leader, Ms Carmen Quinones, who said Ms Patton was with her at the Frederick Douglass Houses in Manhattan and wanted to talk to residents about the housing authority's performance.

Only after the questioning ended were the four tenants told that the interview was for the Republican Party, Ms Perez said. But she said she was never told that it was for the convention.

Ms Patton declined to be interviewed, saying that she was travelling. But she issued a statement denying that she misled the four tenants, saying that they knew that their interviews would be shown at the convention "to increase awareness of the inhumane conditions that Mayor de Blasio has allowed for far too long".

"Each participated regardless of political party because they recognised the importance of having a voice on the national stage and the undeniable improvements that have transpired under this administration," she said.

She said the video had been vetted and cleared for Hatch Act violations by the White House.

She said that she had spoken with all four tenants on Friday and that they were upset with the way the Times was "twisting their words".

In a separate interview, Ms Quinones said she talked to Ms Patton on Friday afternoon and was comfortable with how she was being portrayed by the Times. She said she was disappointed that her words were twisted to support Mr Trump.

Ms Perez and a third tenant, Mr Manny Martinez, said they had not spoken with Ms Patton on Friday and did not know what she was talking about.

Explaining how the video came about, Ms Quinones confirmed that Ms Patton had reached out to her about assembling tenants to talk about the authority.

But Ms Quinones said she did not realise until the cameras started and the questions began that Ms Patton had actually recruited the tenants for interviews for the party.

Ms Quinones said she wished that she had been told in advance that the clip would be shown at the convention. She said she was a lifelong Democrat who plans to vote for Mr Joe Biden in November. She was interviewed on Friday as she marched in Washington at the Get Your Knee Off Our Necks rally, sponsored by another Trump target, Reverend Al Sharpton.

When asked whether she was concerned about being misled, Ms Quinones said, "It is what it is."

She added that she decided to use the opportunity to highlight what she said were extensive problems at the housing authority under Mr de Blasio.

"For me, this was not about party but for us to make the national stage," she said. "They were the only ones that offered. My own party didn't offer."
