Poilievre's decision not to go through security screening means that no one in the party is in a position to act on the intelligence or challenge its accuracy, said Trudeau.
"The decision by the leader of the Conservative Party to not get those classified briefings means that nobody in his party, not him, nobody in a position of power knows the names of these individuals and can take appropriate action," he said.
"It also means nobody is there to stand up for those individuals if the intelligence is shoddy or incomplete or just allegations from a single source."
