Leonardo DiCaprio has responded to Brazil president Jair Bolsonaro’s wild accusations that he’s been bankrolling the Amazon rainforest fires.

Bolsonaro made the unfounded claims on Friday. Bolsonaro said the actor was part of an international “campaign against Brazil.” He offered no evidence to support his claims, which many took as an effort to deflect blame for the disaster from his own government.

The remarks are also believed tied to the arrest of four volunteer firefighters earlier this week who were accused of setting fire to a portion of the forest. They allegedly were attempting to boost fundraising for an unnamed international non-governmental organization, or NGO, that was rumored to have ties with DiCaprio.

Today, DiCaprio responded on Instagram. “While worthy of support, we did not fund the organizations targeted. I remain committed to supporting the Brazilian indigenous communities, local governments, scientists, educators and general public who are working tirelessly to secure the Amazon for the future of all Brazilians.”

EARLIER:: Jair Bolsonaro, the populist Brazilian nationalist president sometimes referred to as the “Trump of the Tropics,” has accused actor Leonardo DiCaprio of financially backing the fires that have torched the Amazon rainforest in that country.

So far, Bolsonaro’s unsubstantiated attack has drawn scorn from politicians and activists.

Bolsonaro made two claims on Friday against DiCaprio, first using Facebook and then reportedly telling supporters: “This Leonardo DiCaprio’s a cool guy, isn’t he? Giving money for the Amazon to be torched.”

He earlier made a similar claim in a Facebook live broadcast. “Leonardo DiCaprio, dammit, you’re collaborating with the burning of the Amazon,” Bolsonaro said, saying the actor was part of an international “campaign against Brazil.” He offered no evidence to support his claims in either instance.

The remarks are believed tied to the arrest of four volunteer firefighters earlier this week who were accused of setting fire to a portion of the forest. They allegedly were attempting to boost fundraising for an unnamed international non-governmental organization, or NGO, that was rumored to have ties with DiCaprio.

The firefighters were released Thursday after public outrage over the arrests.

On Thanskgiving, Bolsonaro’s politician son, Eduardo, claimed on Twitter that DiCaprio donated $300,000 to“the NGO that set fire to the Amazon” and accused the conservation group WWF of paying the NGO for photographs of the burning forest. The WWF rejected the attacks on its partners “and the lies involving its name, including a series of lie-based social media attacks, such as the purchase of photographs linked to a donation from the actor Leonardo DiCaprio,” it said in a statement.

DiCaprio pledged $5 million to help fight the huge fires in the Amazon region last summer. Bolsonaro and other conservative politicians have been at odds with environmentalists in the region.
