Rosie O'Donnell jabs Trump as 'such a creep' after back-to-back mass shootings

Hollywood is calling on Washington, D.C., to make changes after two mass shootings in Dayton, Ohio, and El Paso, Texas, left at least 29 dead and 52 injured in less than 24 hours over the weekend.

Former "View" host Rosie O'Donnell called President Donald Trump "such a creep" after he was seen visiting a wedding at one of his golf properties over the weekend. She included a tweet that ripped the president for his presence at the celebration amid the shootings.

Rihanna also criticized the president for refusing to call the shootings terrorist attacks.

"Imagine a world where it’s easier to get an AK-47 than a VISA," she wrote in an Instagram post. "Imagine a world where they build a wall to keep terrorists IN AMERICA!!! My prayers and deepest condolences to the families and loved ones of all the victims and the communities affected and traumatized, from Texas, California, and Ohio! I’m so sorry for your loss! Nobody deserves to die like this! NOBODY!"

Jamie Lee Curtis repeatedly wrote the phrase "Assaultweaponban" in a tweet.

Speaking Monday on the "Today" show, Eva Longoria teared up, thinking about her family members who live in Texas.

"I think the problem is people aren't really getting outraged because it's not their child or it's not their state, or it's not their mom," she said. "But you have to think 'this was somebody's mom. It is somebody's family members. It is somebody's friend'... It is a mental health problem. I get that. But it’s also a gun problem.”

She continued: “Being from Texas too, I understand the second amendment. I grew up with, you know, that environment. It’s not about taking guns away. It’s about making sure responsible people have them.”

John Oliver addressed the shootings on "Last Week Tonight" Sunday and slammed Trump for "creating an environment" where "white nationalism and anti-immigrant" rhetoric "can fester and indeed thrive."

"When it comes to gun control, I know it can feel like everything's been said before," he told his audience. "But while the depressingly familiar numbness that you may be currently feeling can help you handle the pain in the short term, in the long term, it can actually be a real problem because unless something hurts as much as it's supposed to, nothing gets done about it."

"Star Trek" actor George Takei slammed lawmakers who accept money from the National Rifle Association: "We need to understand that so long as politicians can (receive) unlimited campaign funds from lobbyists, things like sensible gun safety legislation can't get passed."

"America is a country that prides itself on freedom, but we can't leave our homes without the thought of possibly being gunned down," "Avengers" actor Mark Ruffalo tweeted. "Where can anyone go in large groups anymore without fear?"

"Until we change gun laws this will keep happening," tweeted Cyndi Lauper on Sunday. "In the last month we have had how many mass shootings? Again in New Zealand they banned all assault weapons and there are no more mass shootings. Republicans need to wake up."

Actress Rosario Dawson, who is currently dating Democratic presidential candidate Sen. Cory Booker, called on others to work toward change: "Whatever you are not changing you are choosing."

"Remember how angry you are today," wrote "Family Guy" creator Seth MacFarlane. "Pack it up, store it, and pull it out again on every Election Day, every time. The people blocking common-sense gun legislation don't just materialize out of thin air. We vote them in, actively or by inaction. We can vote them out."

Actress and activist Alyssa Milano slammed Senate Majority Leader Mitch McConnell and Republican leadership in general for being "'pro-life' when they won't vote for a bill -- that has already passed in the house -- which would make the country safer from gun violence."

Julianne Moore also tweeted at McConnell: "do you have the courage to save lives?"

Milano also called on Walmart, the store where at least 20 people were killed Saturday morning, to stop selling guns, calling it a "great opportunity to take a true leadership position."

"Captain America" star Chris Evans shared a video of President Donald Trump in May speaking to a crowd in Florida about building a border wall, in which he rhetorically asked "How do you stop these people?" in reference to immigrants and chuckled after a member of the crowd shouted "Shoot them!"

"Just a reminder," Evans tweeted Saturday night. "He laughed. Then he made a joke. Then he mugged for the camera as the crowd applauded. Then he just kept right on talking."

"SO ..Shootings are now hourly," tweeted Henry Winkler on Saturday. "We are getting so good at them.. and our representatives say nothing .. They are good at that too."

"Gilmore Girls" star Lauren Graham wrote Saturday that she understands "why people might want to legally own a rifle for hunting or a hand gun for home protection," but does not get why "we allow civilians to purchase assault weapons."

"What do we expect they'll be used for besides the heartbreaking obvious?"

"What will it take?" wrote "Seinfeld" alum Jason Alexander early Sunday morning. "Honestly, what will it take? #ElPaso #Dayton."

"PLEASE FOR THE LOVE OF ALL THINGS... JUST LOVE ONE ANOTHER," tweeted "Breaking Bad" actor Aaron Paul.

Reese Witherspoon wrote: "There are no words. My heart breaks for the friends and families of the El Paso victims. Praying for all of you. We must do more to stop these senseless acts of gun violence."
