Viewers watching the third night of the Democratic National Convention couldn’t help but notice a covert message behind Senator Elizabeth Warren as she delivered her speech.

Warren’s subtle tribute to the Black Lives Matter movement was mocked on social media after she had the letters BLM laid out with childrens toy alphabet blocks in the background of her video address to the DNC.

RT reports: The progressive senator spoke to the Democratic National Convention on Wednesday from a childhood education center, located in Springfield, Massachusetts.

Warren’s speech was mainly about her support for Joe Biden’s presidential bid and the problems she had with Donald Trump’s response to the Covid-19 pandemic. However, she apparently decided to include some topical symbolism by arranging toy alphabet letters behind her to spell BLM, meaning “Black Lives Matter.”

The decision came under fire following her address, as people derided the anti-racist Easter egg for not being substantive or at least subtle.
