All presidents regardless of party need to show clear proof that they are not being influenced by domestic or foreign interests. To do that, the candidates or sworn in president needs to disclose their tax return. This is not a party issue, it's an issue of protection for all Americans. There is literally no reason to prevent this unless you desire to conceal domestic and foreign influence for yourself or the president. Please support this push for oversight and transparency of the executive branch for the current president and all others to come.
