Correct, and the US supported the White Russians.
The author includes his accusation as the last sentence in a paragraph referring to WWI and 1918, which makes it incorrect.
If he had referred to little more than a decade later, the US did offer aid to the Reds both politically and promotionally.
At best it's sloppy, at worst it's untrue.
What he’s probably referring to is Jacob schiff and his secret monetary support of Trotsky and Lenin, which Wilson certainly knew about if not outright supported.
The US send 4 regiments, all infantry, to guard military stores at Murmansk and Vladivostok, armed with Mosin-Nagent rifles (manufactured by Remington for the Tsar). There was concern that German forces would be able to capture the materiel, and with the Bolshies signing a treaty with the Germans, use the materiel against the Allies.
The two regiments near Murmansk were sent south, and gained a great deal of space. Their commanders took instruction from the British official on the scene, to their shame. They set up a network of interlocked fortifications that were very effective against the Red Army.
The two regiments near Vladivostok secured and operated the Trans-Siberian railroad. The Czech Legion was one unit that was able to escape from Soviet Russia.
