‘Grandiose + stupid’: The internet drowns Trump in mockery over his latest outburst on Russia collusion

President Donald Trump went off on another Twitter rampage Monday morning about Russia collusion -- and social media users heaped scorn and derision on him.

The president accused his predecessor, Barack Obama, of doing "NOTHING" to stop Russian efforts to interfere with the 2016 presidential election, which Trump has previously disputed, and claimed that amounted to collusion and obstruction.

Trump and his associates are under investigation by Congress and special counsel Robert Mueller for allegedly colluding with Russia to tip the election and for obstruction of justice.
