During his remarks this afternoon, House manager Adam Schiff is focusing in on how delaying aid from Ukraine emboldened Russia.
He called Russia's invasion of Ukraine "a threat to the peace and security of Europe."
Schiff said that if Congress had not "voted overwhelmingly on a bipartisan basis for military assistance" to Ukraine it would have invited "further Russian adventurism" in the country.
"Deterring Russia requires persistence. Not just one military aid package or one Oval Office meeting, but a sustained policy of support for our partners," Schiff said. "We only deter Russia by consistently demonstrating support for our friends, friends like Ukraine."
In his argument, Schiff cited Ronald Reagan's Secretary of State George Shultz compared diplomacy and alliance management to gardening.
"[Schultz] said, quote, if you plant a garden and go away for six months, what have you got when you come back? Weeds. Diplomacy, he said is kind of like that. You go around, talk to people. You develop a relationship of trust and confidence, and then if something comes up, you have that base to work from," Schiff said.
He aded that Trump's decision to transform the military aid package and Oval Office meeting into "leverage" was "the equivalent of trampling all over Shultz's garden."
