I disagree. A confident leader that can project calm and a unified message and show you that things will be handled helps enormously with rallying people. The panic is caused by obvious lies, general secrecy and scarcity of direction and information. Concerted efforts by the administration to limit trustworthy news sources which are desperately needed in these times.
The volume of lies and attacks on the press from the beginning of this administration come to roost now. People don't trust him, they don't trust certain news outlets because he said not too. It goes both ways and he absolutely can be blamed for that. He choose to prioritize the building of a racist wall stealing money from the military so he could say I fulfilled a campaign promise. To preparing us by funding the CDC.
