You may want to write your Representative to let him or her know how you stand on opening an Impeachment Inquiry into President Trump. Many have a contact form on their websites. Here is the text of my letter:

Thank you for standing up to President Trump in support of our Constitution and country. The Impeachment inquiry is especially important. President Trump has violated his oath of office many times (in my opinion). The Mueller report highlighted many of these instances and the latest instances of asking Ukraine and China for political help to slime a potential rival may be even more clear violations.

I hope the Impeachment Inquiry will be successful in uncovering more information about these and possibly additional offences.
