Lula Slams US Visa Revocation

The US decision to revoke the visa of a Brazilian envoy has sparked a diplomatic row. Lula has expressed strong disapproval of the move, calling it 'irresponsible'. The Brazilian President's reaction suggests that the relationship between the two countries may be strained. The revocation of the visa is likely to have significant implications for bilateral ties. The US has not yet commented on the matter, but it is expected to respond soon.
