(CNN) The effects of Donald Trump's cruel presidency will take years, if not decades, to undo. And when history is written, his tenure in the White House will likely be cited as the darkest in modern American presidential politics.

While the list of the President's despicable comments is already quite long, this weekend Trump added yet another. On Saturday, Trump used two young Guatemalan children who recently died in US custody to score political points.

He tweeted , "Any deaths of children or others at the Border are strictly the fault of the Democrats and their pathetic immigration policies that allow people to make the long trek thinking they can enter our country illegally." Trump then used the tragedy to argue for his beloved wall: "If we had a Wall, they wouldn't even try!"

In tweeting this way about these two children, Trump reduced them to pawns in his larger political game. And while Trump is not the first politician to politicize the immigration issue -- sadly, politicians on both sides of the aisle have done so -- his tweets are particularly stinging because he refused to see these children's humanity.

And worse yet, he tried to prevent the American people from seeing them for who they were -- innocent young children. If we did, that would likely cause more Americans -- possibly even some Trump supporters -- to be outraged at the President's callousness.
