Get your daily scoop of what State of the Union is watching today, October 22, 2014.
1. Canada shootings. Canadian police are investigating three shootings that occurred across Ottawa. The first took place at the National War Memorial, where the gunman killed a soldier. The other shootings occurred near the Rideau Centre and inside the Canadian Parliament building, which is on lockdown. The gunman who opened fire in Parliament was shot dead by the legislature's Sergeant-at-Arms, Kevin Vickers. Assistant Police Commissioner Gilles Michaud described the incidents as a "dynamic and unfolding situation" and urged Canadians to be vigilant and report any suspicious activity to police. Today's attacks come just three days after a man who Canadian authorities say was "radicalized" was shot to death in Quebec after hitting two Canadian soldiers with his car, killing one of them.
2. Ebola in the U.S. As of today, air passengers flying to the United States from the West African countries hardest hit by Ebola will be restricted to entering through five airports. Passengers from Liberia, Sierra Leone and Guinea will only gain entry through New York's JFK, Newark's Liberty, Atlanta's Hartsfield, Chicago's O'Hare and Washington, D.C.'s Dulles. Those five airports have bolstered their passenger screening procedures for the virus. So far, the Obama administration has resisted calls to impose a travel ban on the three affected countries. Meanwhile President Obama called health workers at Texas Health Presbyterian Hospital in Dallas to thank them for their efforts in the Ebola fight. The medical facility treated Ebola patient Thomas Eric Duncan, who eventually died. Two nurses who cared for Duncan also contracted the virus. One is being treated at Atlanta's Emory Hospital, while the other is under medical care at the National Institutes of Health in Maryland.
3. The girls who wanted to join ISIS. Three teenage girls from Denver skipped school and flew to Europe for the purpose of joining ISIS. The girls, two of whom are sisters, were intercepted at Germany's Frankfort Airport. Their parents notified the FBI when they discovered the girls' passports gone and $2,000 missing. The girls' parents say they had no idea their children planned to travel. The teenagers were released into the custody of their parents and won't face criminal charges. It is unclear why they wanted to join ISIS.
