It is illegal in the USA for any political candidate to accept any contribution of value from any foreign government representative or agency. This applies to any attempt to obtain such "contributions of value" by campaign staff or others (like family) acting on behalf of the candidate too.
The President tweets the meeting was not illegal. Another lie.
Trump continues to interfere in the investigation into Russian interference in the election, because his narcissistic ego cannot admit he didn't win unassisted. This insatiable need of his to self-promote, and thereby feed his own ego regardless of the falsehoods necessary, also compelled him to make false statements about three million illegals having voted against him and the absurd claim despite photographic evidence that he had a larger crowd at his inauguration than Obama..
His self image is that of an infallible character who deserves all the accolades of everyone else, calling all exposures of his failures "fake news" in denial of his own lying and inadequacies as a person.
This is Malignant Narcissism defined...
He will persist regardless of the facts arrayed against his ranting and fantasies of having plans that he never produces.
He imagines all his failures are due to someone else's inadequacies, whether it's the journalists who uncover and report his incessant lies as inversions of his former statements or simply contrary to facts, or the underlings who cannot deliver the things he demands because they'd be in breach of the laws of the nation if they did.
He disowns and attacks people he formerly publicly and on video called "excellent" like Papadopoulos.
He calls Omarosa a "dog" now, yet accepts no part in giving her the opportunity to disappoint him, even though he'd fired her three times previously and admits he hired her only because of her effusive praise for him. That is the worst possible reason for a hiring a presidential staffer...ever!
The article below adds to these observations with instances where Trump betrays his own irrepressible need to attack, fire, demean disparage and insult people who rightly take their oath of office to defend the nation and its constitution more seriously than his demands for personal loyalty to him.
