THIS MORNING

All the things Trump doesn't like in one tweet:

President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?' Romney: 'Unthinkable and unacceptable' to not commit to peaceful transition of power Two Louisville police officers shot amid Breonna Taylor grand jury protests MORE slammed the media, former Vice President Joe Biden Joe BidenBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?' Democratic groups using Bloomberg money to launch M in Spanish language ads in Florida Harris faces pivotal moment with Supreme Court battle MORE and former President Obama this morning on the day of Biden's first campaign rally. http://bit.ly/2vrP5Fk

Trump tweeted: "The Media (Fake News) is pushing Sleepy Joe hard. Funny, I'm only here because of Biden & Obama. They didn't do the job and now you have Trump, who is getting it done -- big time!"

Not a fan of union leaders:

This morning, President Trump slammed union leaders after former Vice President Joe Biden received an endorsement from a major firefighters' group. http://bit.ly/2V4ENdM

Trump tweeted: "I'll never get the support of Dues Crazy union leadership, those people who rip-off their membership with ridiculously high dues, medical and other expenses while being paid a fortune. But the members love Trump. They look at our record economy, tax & reg cuts, military etc. WIN!"

He later added: "The Dues Sucking firefighters leadership will always support Democrats, even though the membership wants me. Some things never change!" http://bit.ly/2DCok5y

IN THE WHITE HOUSE

The Russia problem isn't going anywhere:

Secretary of State Mike Pompeo Michael (Mike) Richard PompeoTreasury sanctions individuals, groups tied to Russian malign influence activities Navalny released from hospital after suspected poisoning Overnight Defense: Pentagon redirects pandemic funding to defense contractors | US planning for full Afghanistan withdrawal by May | Anti-Trump GOP group puts ads in military papers MORE predicted that Russia will try to interfere in U.S. presidential elections for decades to come. http://bit.ly/2VyklkL

Where he said this: The Hill's editor-in-chief Bob Cusack interviewed Pompeo this morning at an event hosted by The Hill.

In Pompeo's words: "It goes without saying they were a threat to our elections in 1974, they interfered in our elections in the '80s ... The fact that this town seemed shocked by the fact the Russians don't care for us -- in that case the Soviet Union -- I find stunning." He also said: "We should expect in 2050, the Russians will still be at it still."

On Thursday: Barr is scheduled to testify before the House Judiciary Committee.

^ Well...: Over the weekend, Barr warned House Democrats that he might not show up for the House hearing unless the proposed format for the hearing is changed. http://bit.ly/2LeSRwG

ALSO HAPPENING IN THE HOUSE AND SENATE THIS WEEK:

Yemen: "The Senate is set to take up President Trump's veto of legislation cutting off U.S. support for the Saudi-led war in Yemen this week, though any override attempt is expected to fall short."

Medicare for All: "The House Rules Committee is slated to hold its first-ever hearing on a Medicare for All bill spearheaded by Reps. Pramila Jayapal Pramila JayapalDHS opens probe into allegations at Georgia ICE facility Progressive Caucus co-chair: Whistleblower complaint raises questions about 'entire detention system' Buttigieg, former officials added to Biden's transition team MORE (D-Wash.) and Debbie Dingell (D-Mich.) on Tuesday.

ON CAPITOL HILL

Spy Kids:

Via The Hill's Morgan Chalfant, "GOP lawmakers returning to Washington are signaling they intend to step up their campaign to look into alleged spying by FBI agents on President Trump's 2016 campaign." http://bit.ly/2J4aQTZ

Timing: "The effort comes as Democrats ramp up their own investigations into the Trump administration and could serve as a bit of GOP counterprogramming to put the spotlight on what Republicans contend is suspicious behavior under the Obama administration."

I can feel the tension bubbling up:

Via The Hill's Alexander Bolton, President Trump is on a collision course with Senate Majority Leader Mitch McConnell Addison (Mitch) Mitchell McConnellFEC flags McConnell campaign over suspected accounting errors Poll: 59 percent think president elected in November should name next Supreme Court justice Mark Kelly: Arizona Senate race winner should be sworn in 'promptly' MORE (R-Ky.) over whether to work with Democrats to compromise on a spending bill. http://bit.ly/2V3Wb23

Why there's tension: Trump does not want the talks to drag on all year and does not want a deal that would increase spending.

Why McConnell wants to avoid a continuing resolution: "He wants to strike a deal to raise defense and nondefense spending, along the lines of what congressional leaders agreed to in the late winter of 2018. And one reason is that under the 2011 Budget Control Act, a continuing resolution would trigger automatic spending reductions known as 'sequestration' that would lead to huge cuts at the Pentagon and to domestic spending."
