Did President Trump say he will override the Supreme Court and make desecration of the flag (including the Confederate one) illegal? No, that's not true, despite what a recent meme claims. The meme was produced by a satirical liberal Facebook page that tries to trick conservatives and Trump supporters into liking and sharing absurdly fake news so fans of the pages can then mock them for it. The story and the Trump quote are not real.
It originated from a meme that appeared on August 28, 2018 in a post on a Facebook page named "America Loves Donald Trump" (archived here) with following caption:
Yaaay Precedent........I got nuthin
The text on the meme read:
President Trump says he will override the Supreme Court and make desecration of the flag illegal!
His order will cover the Confederate flag as well!
Share if you support this incredible decision!
However the Facebook page that posted the meme comes with following disclaimer on its about page:

Nothing on this page is real. It is a collection of the satirical whimsies of liberal trolls masquerading as conservatives. You have been warned.
Constitutionally speaking the President is also not able to override Supreme Court decisions with a simple executive action, he would need the support of Congress so he can have legislation passed for that (and he possibly might need to get an amendment to the Constitution ratified first). So this news is definitely fake, this is not something the President can just decide to do.
