The U.S. Secret Service wants a word with the man who threw glitter at President Donald Trump at Thursday night’s rally in Minneapolis.

“Today the Secret Service visited my house multiple times, visited my family’s house, left multiple notes on my car and phone messages,” said Nick Espinosa, 33, of Minneapolis. “I’m a bit surprised they are taking something as harmless as glitter so seriously. Clearly, there was no harm done.”

Espinosa, who threw gold glitter into the air near Trump at the Target Center, said he was trying to send a message.

“I wanted to make it clear that Donald Trump’s hate is not welcome in Minneapolis,” he said.

Espinosa posted on Twitter photos of the Secret Service notes asking that he call the Minneapolis office regarding an investigation.

“I’m not too nervous,” he said. “I think they’re just trying to intimidate me. I think if they were going to press charges, it would look pretty foolish. I would expect it to go away.”

Trump's secret service visited my home twice this morning, pounding on the door and ringing for several minutes. I of course did not answer. Then they visited my family, & left a message on my cell asking to speak to me about #GlitterbombTrump, which I forwarded to my lawyer. pic.twitter.com/dUaJcIlx2v — Nick Espinosa (@CGoHome) October 11, 2019

The agent answering the phone at the Secret Service office in Minneapolis said he could not comment on the incident nor confirm it was being investigated.

Espinosa said an agent was at his house twice, pounding on the door and ringing the doorbell for several minutes.

“I, of course, did not answer,” he said. He has contacted a lawyer.

Glitter bombing became a popular form of protest during the 2012 presidential election cycle, particularly used by LGBT activists.

Espinosa has a history of throwing things at members of the Republican Party. He dumped glitter on Newt Gingrich in 2011 and showered Mitt Romney in Eagan in 2012.
