This sword was mightier than politics.

Sen. Bernie Sanders posted a tribute to self-made billionaire Ross Perot, who died Tuesday — and revealed the two-time, third-party presidential candidate once gifted him a bejeweled blade for his work on a veterans bill.

“Ross Perot was a champion for veterans’ rights and ahead of his time on disastrous trade policies,” Sanders tweeted. “During his campaign, he explained, in depth, how he would address our national problems and spurred serious discussion.”

“Ross Perot was a one-of-a kind American,” Sanders added. “He will be missed.”

The 2020 Democratic presidential contender’s tweet was accompanied by an image of the sword, meant to replicate King Arthur’s legendary weapon “Excalibur” mounted on a plaque.

The plaque has Perot’s signature and a longer message that reads, in part: “Presented to Congressman Bernard Sanders, with deep appreciation for your many years of extraordinary leadership to provide proper medical treatment to our military forces who were wounded by chemical weapons in Desert Storm.”

There’s also a quote from Winston Churchill — “never give in, never give in, never never never.”

Democratic socialist Sanders referenced the unusual gift from the Texas capitalist in a 2015 New York Times article.

“That is from Ross Perot,” Sanders told the Times. “He said: ‘When media gives you a problem, take it out! Threaten them!'”
