(CNN) -- Welcome back from what we hope was a good weekend for you. Here are the 5 things you need to know today to Get Up to Speed and Out the Door.

1. Turkey referendum

Turkish President Recep Tayyip Erdogan is claiming victory in a controversial referendum that gives him sweeping powers by ending the current parliamentary system. (The office of the president was meant to be an impartial one.) The referendum also means Erdogan could stay in office until 2029. But it passed only narrowly and there are accusations of voting irregularities, voter intimidation and biased media coverage. So opponents will take to the streets today to protest.

2. Facebook killing

The search has widened to five states for a man who police say killed someone in Ohio and then posted the video on Facebook. Steve Stephens is accused of killing a 74-year-old man outside of Cleveland. Stephens is considered armed and dangerous. He told his mother he was shooting people at random because he was mad at his girlfriend.

3. North Korea

Vice President Mike Pence is warning North Korea not to test the resolve of the US or the strength of the military. He says the "era of strategic patience is over" and the US will stop any attack that might come from the North. The regime tried to test fire a missile over the weekend, but officials think it blew up right after launch.

4. White House

Tomorrow is Tax Day, so thousands of Americans thought it was a good time over the weekend to remind us that Donald Trump still hasn't released his tax returns. The White House reaction? Trump's win proves people don't care. The marches were mostly peaceful, except in Berkeley. Meanwhile, the 2020 election is a ways off, but the White House is already busy raising cash for Trump's re-election campaign.

5. Arkansas executions

The state's plan to kill eight inmates in 10 days is off for now. A federal judge blocked the executions, saying the prisoners will probably succeed in proving the state's proposed method of execution -- lethal injection -- is unconstitutional. Arkansas has appealed. The state says it wants to execute the inmates before its supply of lethal injections drugs expires.
