Arthur Moledo do Val (born 21 August 1986 in São Paulo) is a Brazilian politician, activist member of Free Brazil Movement, YouTuber and entrepreneur.

He is a defender of mostly classical liberal ideas and uses his channel MamãeFalei on YouTube to spread political news and opinions among his followers, which are more than 2.5 million subscribers.

[5] The activist says that his question regarding the Brazilian economy and politics began in his younger years, inspiring him to create the channel "Mamãefalei" in June 2015.

[6] Arthur took the opportunity to expose one of the main points of his job in the following year, in 2016, which would include the criticism to the blind political militancy.

Arthur said that such a study didn't exist and asked for Fux's presence, saying that he would be involved with important questions such as the unconditional right given to the public service.

And that's what we need to trust more than in a bureaucrat with a pen.On 23 August 2019, Arthur stated he would leave Democrats to run for Mayor of São Paulo in the 2020 election.

[8] In February 2020, do Val, along with the elite of the Free Brazil Movement, joined the party Patriota (PATRI) and reaffirmed his intentions to run for Mayor of São Paulo.

Thais Bilenky, writing for Folha de S. Paulo, considered that, in the act, Ciro touched the activist's neck, alleging that it's not possible to measure the intensity of the supposed slap.

[13] Yet, the specialist in micro facial expressions and body language, Vitor Santos, certified by Paul Eckman Group,[14][15] evaluated the hypothesis of manipulation on the video of the struggle, analysing the footage of the fact and concluding that Arthur was really assaulted.

[21] Damares Alves, Minister for Family, Women and Human Rights and other São Paulo State Parliamentarians called for do Val's immediate resignation.
