I think it's a reference to Putin leaving Trump waiting on the diplomatic call last week

It's the "Red Phone" world leaders supposedly use for direct contact between each other.

I guess it fits this drawings narrative because Putin uses Trump's gullibility in conversations (Trump thinks he and Putin can be partners) to make him do his bidding.

From Wikipedia:

The Moscow–Washington hotline (formally known in the United States as the Washington–Moscow Direct Communications Link; Russian: Горячая линия Вашингтон – Москва, romanized: Goryachaya liniya Vashington–Moskva) is a system that allows direct communication between the leaders of the United States and the Russian Federation (formerly the Soviet Union). This hotline was established in 1963 and links the Pentagon with the Kremlin (historically, with Soviet Communist Party leadership across the square from the Kremlin itself). Although in popular culture it is known as the "red telephone", the hotline was never a telephone line, and no red phones were used.
