A trial without witnesses is a sham trial & the American people know this. There is ample evidence of Trump’s wrongdoing. What if Obama or Hillary had bribed foreign governments to dig dirt on an opponent (based on a known conspiracy theory) ? As your constituent, I expect you to act in a professional and non partisan manner, follow the constitution & listen to all evidence no matter the consequences. Instead of protecting him at all cost & thinking in the short term about your career, how will your name go down in history? Will it be protecting a corrupt President or protecting the country? Your choice.
