Trump’s pick to lead DHS faces questions about his temperament at Senate hearing

What we're covering
• DHS confirmation hearing: Sen. Markwayne Mullin is testifying before a Senate committee to be the next Homeland Security secretary. In a tense start, Sen. Rand Paul accused the Oklahoma senator of having “anger issues.”

• “I shouldn’t have said that”: Mullin admitted that his early comment calling Alex Pretti a “deranged individual” was a mistake. Pretti, an ICU nurse in Minnesota, was killed by immigration officers in January.

• Global threats hearing: Meanwhile, President Donald Trump’s intelligence chiefs are testifying before a Senate hearing about the Annual Threat Assessment, the first such report not to mention foreign threats to US elections since Russia’s meddling in the 2016 election. Director of National Intelligence Tulsi Gabbard said the Iranian regime “appears to be intact, but largely degraded.” You can follow CNN’s live coverage on Iran here.
