How many different instances has Trump been defiant to denounce (or sanction) Russia regarding Russian wrongdoing related to US national security (and intelligence) that we know about in the public eye since he's been POTUS?

For example, currently he is being silent (or blaming other countries) for the cyberattacks the US intelligence says they have proof tracing it back to Russia that his own Secretary of State and Attorney General publicly say they agree with the US intelligence reports yet he refuses to denounce Russia himself in public.

Does anyone know how many different instances of such Russian wrongdoing since he's been in office he has refused to agree with others in the US intelligence community or his cabinet and such to sanction or publicly denounce Russia?

## Potential Objective Measures (but not limited to) ##
 - The US intelligence community and/or the administration's cabinet publicly denouncing 
 - Others providing evidence of Russian wrongdoing
 -  Issues that other NATO members have responded with regard to Russia
