As reported by the Daily Mail, Mulvaney previously said that his online series chronicling his daily life of what it's like to be a woman has garnered enough income to pay for the surgeries.
"For some of these major corporations, I was actually their first trans creator," Mulvaney said.
"It's exciting to make money to support myself since I lost my job and to have my transition surgeries be covered too," he concluded.
Mulvaney eulogized his face in a dark, comedic manner before undergoing surgery, making light of the serious procedures.
"Dear sweet face, you did me good!" Mulvaney said before stating that the previous face was "still a friend."
"If we had stuck it out together forever we would've made it work," the transgender woman continued, adding strange remarks such as "please don't feel like you failed" and "I can assure it's me, it's not you."
The comments, seemingly meant to be self-uplifting and inspirational, also reveal a level of sadness, with comments such as "you sparked a sadness much too often that most will never relate to."
According to John Hopkins Medicine, the procedures can include: forehead and hairline contouring, brow lift, eyelid lift, rhinoplasty, jaw contouring, chin reduction, liposuction, and tracheal shaving (Adam's apple).
In an interview with Joe Biden, the president told Mulvaney that he doesn't think "any state or anybody should have the right to" limit such treatments, stating that "sometimes they try to block you from being able to access certain medicines, being able to access certain procedures, and so on."
"As a moral question and as a legal question, I just think it's wrong," the president added.
