@cbsnews: One person was arrested near the White House on Monday after a car drove onto a sidewalk. In a separate incident, another person was arrested after jumping a barricade at Lafayette Park, in front of the presidential compound. U.S. President Donald Trump was at home during the incidents. The White House was briefly placed on lockdown, and roads around the park were closed. “The driver was combative with law enforcement but was quickly placed under arrest,” a Secret Service spokesperson said in a statement. “Around the same time, a second individual jumped a barricade near the northwest corner of Lafayette Park. That individual was also quickly placed under arrest.” The Secret Service said both incidents were under investigation, though it was not clear whether they were related.
