This top teacher expertly trolled Donald Trump with her dress without him realising.

On Wednesday, a woman by the name of Mandy Manning – an English and maths teacher from Washington – was awarded America’s 2018 National Teacher of the Year.

Manning teaches at Joel E. Ferris High School’s Newcomer Center in Spokane, Washington, which has a large focus on teaching immigrants and refugees and it’s right about now I feel you can see where this is going.

You see, Manning was honoured at the White House by President Trump, a remarkably unhelpful force in the areas of supporting immigrants and refugees.

We need to talk about the fact the President phoned in live to a television show and rambled for 31 minutes. Post continues after audio.

So, she popped on a dress and littered the top section with badges supporting her favourite causes. She wore pins representing the Women’s March, the Peace Corps, gay pride, the National Endowment for the Arts and Trans Equality Now, giving a blistering lesson in how to protest politics without saying anything at all.

Manning also brought along a stack of letters from her students to the ceremony, passing them onto Trump in a private moment and asking him to read them if he could.

“I just had a very, very brief moment so I made it clear that the students that I teach ... are dedicated and focused,” Manning said in an interview with The Associated Press. “They make the United States the beautiful place that it is.”

In a separate interview with The Washington Post, Manning said the letters sought to outline the "rigorous and difficult process" of coming to the United States as refugee.

"The thing about our immigrant and refugee students is that they have this innate hopefulness," she said.

"They have gone through very, very difficult experiences, but they see coming to the United States as an opportunity. They feel that they can have dreams, and that they can potentially achieve those dreams. It’s really quite beautiful, actually, because no matter what — no matter what they experience — they still have this hope, this resilience."
