Trump and Klobuchar exchange scathing tweets

After Sen. Amy Klobuchar tossed her hat in the ring to be the Democratic nominee for the 2020 presidential race, President Donald Trump took to Twitter to remark on her speech.

"Well, it happened again," Trump tweeted. "Amy Klobuchar announced that she is running for President, talking proudly of fighting global warming while standing in a virtual blizzard of snow, ice and freezing temperatures. Bad timing. By the end of her speech she looked like a Snowman(woman)!"

Klobuchar then tweeted back.

"Science is on my side," she said, responding to the President. "Looking forward to debating you about climate change (and many other issues). And I wonder how your hair would far in a blizzard?"

The snowy weather didn't stop Amy Klobuchar

Democratic Sen. Amy Klobuchar entered the 2020 presidential race at an outside event in freezing, snowy weather in Boom Island, Minneapolis. 

“Now, we don’t let a little snow stop us. We don’t let a little cold stop us. Like, are you guys even cold?” Klobuchar said, to which the crowd shouted, “No!”

It was 16 degrees and snowing heavily when Klobuchar took the stage. The senator was not wearing any gloves.

“Now when I said that elected leaders should go not just where it’s comfortable but also where it’s uncomfortable, this is what I meant,” Klobuchar said, raising her arms and gesturing at the snow as it piled on to her and the crowd gathered before her.

The senator's team ordered 100 gallons of hot chocolate and 100 gallons of apple cider for the event and volunteers handed out packs of hand warmers as people entered the park. 

After her speech, Klobuchar spoke to CNN and said, “What makes me unique is I did this announcement speech in the middle of a blizzard and I think we need people with grit -- I have that grit.” 

President Donald Trump weighed in on Klobuchar's announcement and took a shot at her pledge to fight climate change.

"Amy Klobuchar announced that she is running for President, talking proudly of fighting global warming while standing in a virtual blizzard of snow, ice and freezing temperatures. Bad timing," Trump tweeted. 

"By the end of her speech she looked like a Snowman(woman)!" he added.

During her announcement speech earlier Sunday, Klobuchar told the crowd: “The people are on our side when it comes to climate change. Why? Because like you and I, they believe in science. That���s why in the first 100 days of my administration I will reinstate the clean power rules and gas mileage standards and put forth sweeping legislation to invest in green jobs and infrastructure. And on day one, our country will rejoin the international climate agreement.”

When asked by CNN after her speech if she was tough enough to take on Trump, Klobuchar pivoted back to the snow falling around her.

“I am tough enough to take on Donald Trump,” she said. “I would have liked to have seen him sitting here in the snow for an hour giving this speech.”

Klobuchar addresses foreign policy in 2020 launch

Sen. Amy Klobuchar emphasized the need to stand with foreign allies and face international problems as well as opportunities during her 2020 campaign launch, Sunday.

The Minnesota Democrat alluded to President Donald Trump in her launch speech, saying that U.S. military and intelligence officials “deserve better than foreign policy by tweet.”

“We must respect our frontline troops, diplomats, and intelligence officers … They deserve better than foreign policy by tweet,” Klobuchar said.

Sen. Amy Klobuchar enters presidential race: 'I am running for you.'

Sen. Amy Klobuchar has joined the increasingly crowded Democratic race for President.

Standing in the snow in Minneapolis, she said, “On an island in the middle of the mighty Mississippi, in our nation’s heartland, at a time when we must heal the heart of our democracy and renew our commitment to the common good, I stand before you as the granddaughter of an iron ore miner, the daughter of a teacher and a newspaperman, the first woman elected to the United States Senate from the State of Minnesota, to announce my candidacy for President of the United States.”

Klobuchar told the rally the "sense of community is fracturing across our nation right now, worn down by the petty and vicious nature of our politics. We are all tired of the shutdowns and the showdowns, the gridlock and the grandstanding.”

"Today we say enough is enough. Our nation must be governed not from chaos but from opportunity. Not by wallowing over what’s wrong, but by marching inexorably toward what’s right.”
