Tulsi Gabbard, President-elect Donald Trump's nominee to oversee US intelligence, toured Capitol Hill this week looking to reassure some Republican senators who have withheld their support so far and appeal to any Democrats who might be persuaded to back her.

Gabbard's priorities as director of national intelligence, she has told senators, would include China's cyber threat and fentanyl trafficking at the border while delivering more relevant intelligence reports, according to a person familiar with her conversations, who asked not to be identified discussing private meetings.
