( CNN) Donald Trump is a danger to us all. If there were any doubt, his disturbing press conference with Vladimir Putin corroborated it. It's time for leaders of both parties to respond , not just with words but with action.

To that end, we have a suggestion. Why don't those who are tweeting statements of disgust recognize that they are members of the US Congress empowered with tools to do something actually? They can pass legislation( e.g ., better protection for the special advise — or our elections ), refuse to fund Trump's agenda and hold hearings to get to the truth and hold Trump accountable for the outrages of these past days. Any of these actions would speak far more eloquently to Trump and his new best friend Putin than any number of outraged press releases or tweets by GOP leaders.

That is called for because instead of confronting Russian attacks on our republic, Trump used his time at the summit in Helsinki, Finland, to attack the Russia investigation itself. He laid the blame on both sides in an international version of his controversial statements about the violence in Charlottesville, Virginia, last year. He seemed to agree with Putin's idea that the most sensitive aspects of the Robert Mueller investigation should be shared by both the United States and Russia — and that it should be expanded to cover US citizens. Trump has moved to acting openly against American interests and national security.
