As Bolsonaro took selfies with his supporters near the Planalto Palace, the President was questioned by Wilker Leao, a military corporal who has filmed his confrontations with the right-wing leader's supporters and posted them to YouTube.
In the video, Leao can be heard asking Bolsonaro about his alliance with a group of right-wing and center parties called Centrao, which holds a large number of seats in Congress.
Bolsonaro and his leftist challenger, former president Luiz Inacio Lula da Silva, launched their rival presidential campaigns on Tuesday ahead of the October election.
According to a nationwide poll by Folha de S. Paulo newspaper on Thursday night, Lula remains the first choice of 47% of Brazilian voters. Bolsonaro has been up three percentage points since the last poll in July, but the gap is closing.
According to the Globo video, Leao is seen being pushed by an apparent security officer and refusing to leave. He starts to insult the President, calling him a coward and a punk. Let's see if you have the guts to talk to me, Leao says. Documents show Brazil's environment chief approved paving the way through Amazon despite his own agency's warnings. The President can be seen exiting his car saying he wants to talk to Leao. Come here, come here to talk to me, he says, reaching for Leao's phone. Bolsonaro and Leao can be seen speaking calmly after the scuffle. You can talk to me all you want, and you can talk to me all you want. Bolsonaro says something. When I talk to you calmly, when I went there, I was forbidden to go in there again to talk calmly with you, sir, Leao replies. Bolsonaro's press office and Wilker Leao did not respond to CNN's request for comment.
