Senator James Lankford of Oklahoma has hinted that Tulsi Gabbard, President-elect Donald Trump's pick for director of national security, might face tough questions during her Senate confirmation. Lankford, the newly-elected vice-chair of the Senate policy committee, raised concerns over Gabbard's meeting with Bashar al-Assad, the Syrian president accused of war crimes. He also mentioned past comments made by Gabbard that need to be put into full context. Meanwhile, other Trump nominees like Pete Hegseth, the nominee for defense secretary, and Robert F Kennedy Jr, a vaccine skeptic tapped for health secretary, are also under scrutiny.
