Trump cannot be trusted anymore and therefore should be impeached or resign

After his recent trip to Europe it is increasingly clear (as if it wasn't earlier) that Trump is all about Trump and power, he lies, changes his story, and therefore cannot be trusted by we the citizens of the US.

When you have a so-called leader that is not trustworthy or honest, it is time to that leader to be replaced.......therefore, as bad as Pence would be, too, it is time for Trump to go, Pence to then become our so-called president.........
