The Texas Legislature gaveled in just a few short weeks ago. And, while lawmakers typically wait until the waning weeks of the session to get anything done, we're answering some of your questions about what goes on under the granite dome for our TXDecides project.

Malaysian authorities say initial autopsy results show a chemical weapon — VX nerve agent — was used in the fatal poisoning of Kim Jong Nam, older half-brother of North Korea's leader Kim Jong Un.

VX is an odorless substance that can exist as liquid or gas. It can kill within minutes if it's passed through the skin. It is 10 times more toxic than sarin and classified as a weapon of mass destruction.

The war against ISIS is entering a tough new phase, as Iraqi fighters with growing U.S. assistance push into western Mosul, warns the senior American commander in Iraq, Lt. Gen. Stephen J. Townsend.

President Trump has promised to build a wall along the 2,000 miles of the U.S.-Mexico border.

Russian Defense Minister Sergei Shoigu made his way to the Duma, the lower house of parliament, on the eve of Defender of the Fatherland Day. The Feb. 23 national holiday was once known as Soviet Army and Navy Day, and Shoigu, dressed in the uniform of a general, came to boast about the Russian military's latest achievements.
