In one clip, a woman holds a sign reading, "Trump, a symbol of peace. Don't let them kill us," while another shows the same message spray painted in red on a concrete wall.
The woman holds the sign in English while she says in Farsi, "Help, we need HELP."
A viewer sent in a video from Yazdanshahr in Esfahan Province showing protesters standing and resisting in the street as government security forces opened fire.
Addressing Donald Trump, the protester says: "Do something, Trump! If not now, then when? Step forward."
US Senator Lindsey Graham on Monday posted a picture of himself alongside Trump, who was holding a signed "Make Iran Great Again" cap. The President had invoked the slogan on June 22, the day he launched surprise attacks on Iranian nuclear sites.
Another video shows a young man jumping up to paste a sticker reading "Trump Street" in Farsi over a road sign on a wall.
Trump earlier warned Iran that the United States will "hit (Iran) very hard" if security forces kill protesters.
The US president also posed with a "Make Iran Great Again" hat in a picture shared by Republican senator Lindsey Graham.
The MIGA slogan was earlier used by Trump in a post on his Truth Social in June.
"It's not politically correct to use the term, 'Regime Change' but if the current Iranian Regime is unable to MAKE IRAN GREAT AGAIN, why wouldn't there be a Regime change??? MIGA!!" the president wrote at the time.
Also in late December, Israeli minister Gila Gamliel posted a selfie wearing a MIGA cap, tagging exiled Prince Reza Pahlavi and captioning it "Soon."
Elon inspires protesters
A Persian phrase used by Elon Musk in reply to a post by Iran’s Supreme Leader on X also made its way into the ongoing protests in Iran.
Protesters in Chenar village in Asadabad, Hamadan, chanted the phrase — which roughly translates as “what a futile delusion” or “in your dreams”.
Musk used the phrase in response to a post by Khamenei that said, “We will not give in to the enemy.”
