It's because he is the current president of the US and US support it's key for the liberation of Venezuela, she also supported Biden and Kamala Harris, have Kamala Harris won she would have "supported" her. And it's not like she supports Trump, she is not on favor of his policies but she knows his support it's necessary.
I'm Venezuelan and I don't see those acts as against my country, we hate our current government, at this point after 20 years of the same guys ruining our country we are desperate, and military intervention might be the only solution, because they hold all the power and weapons, and don't care that 80%+ of the population are against them. Although most of us hold the opinion that solving the problem by our own hands would be the best option, it seems like it might not be possible like what happened in 2014, and last year and many others. Military intervention might be the only option left that we have.
