"Due to recent events, Mexican Summer and its staff have made a decision to end our working relationship with Ariel Rosenberg AKA Ariel Pink moving forward", a tweet from the label said.
Pink reacted by tweeting that he had attended the rally to show support for President Donald Trump, and explained that he went back to his hotel to take a nap after the event.
The Mexican Summer is also slated to release a series of "Ariel Archives" on January 29th.
He has collaborated with many well-known artists including Miley Cyrus, Charli XCX and Sky Ferreira.
Responding to a Twitter consumer who drew consideration to his attendance, Pink mentioned: " I used to be in DC to peacefully present my assist for the president. "They did not waste time, save friends, now cancel me and reprimand me before they look for you", only to dispel all doubts about his work, wrote the ridiculous slogan" Vote for Trump".
Meanwhile, Pink explained last month that he is "not MAGA", a reference to Trump's platform of "Make America Great Again", but that he stands against President-elect Joe Biden and Vice President-elect Kamala Harris.
