PORTLAND, Ore. (AP) - After a series of hostile threats this year, state officials have increased Gov. Kate Brown's security detail.

Security has been tightened in the wake of the armed occupation of the Malheur National Wildlife Refuge and threats the governor has received since calling for tighter gun laws.

While not all security measures have been identified, some are visible, such as the additional member of the Dignitary Protection Unit. Brown's office has also increased its unwillingness to release her public calendars in advance.

Communications Director for Brown Kristen Grainger says threats to the governor are not new, but this year comments have not just been vocal expressions of dissent. Instead she says Brown has received threats of physical violence and death.
