We need the Senate to take up the cause on three matters of great importance:

• The IRS cannot be allowed to enforce the ObamaCare individual mandate. The law is bad enough already, but IRS enforcement is unacceptable. The tax agency was caught red-handed targeting conservative groups. It should not be allowed to enforce my health care decisions.

• Congress must pass the bipartisan USA Freedom Act (S. 2685), introduced by Sen. Leahy and supported by Sens. Lee and Cruz. Under the Fourth Amendment, the government must obtain a warrant to search Americans. The NSA and other government agencies are not above the law.

• The Export-Import Bank is up for reauthorization in September. The bank gives taxpayer-backed loans to some of the most profitable corporations in the world. Government bureaucrats need to stop picking winners and losers. The Ex-Im Bank needs to be shut down — do not re-authorize it.

Millions of Americans share my views on these important matters. It is not enough to sit by and do nothing.

The Senate must take action to address these three major issues as soon as Congress comes back from August recess.
